Pretty Love Warren: review

Pretty Love Warren at a glance — here’s what you get

Pretty Love Warren is not a single product but two, cast in one piece of silicone. One half is a bent anal plug intended for prostate stimulation. The other is a ring that is placed around the penis and scrotum. The two parts sit together with a fixed arm, and that’s the whole idea: the plug is anchored outside the body by the ring, and the ring is kept in place by the plug. The set includes a wireless remote control.

The manufacturer is Liaoyang Baile Health Care Product Co., Ltd, which sells the product under its premium brand Pretty Love. On the manufacturer’s own product page, the item is named BI-040162W, and the page field "Bar Code" indicates exactly the barcode this review is based on. The specification published there is short but concrete: silicone material, net weight 90 grams, twelve vibration functions, twelve shock functions, wireless remote control, operation via USB charging plus an AAA battery for the remote control, and package dimensions 190 × 145 × 47 millimeters. The manufacturer’s own dimension drawing adds the four measurements that actually matter on the body: 170 millimeters total length, 101 millimeters plug height, 29 millimeters largest width on the plug, and 44 millimeters internal diameter in the ring.

In Sweden, the item is sold by five stores at prices between 299 and 609 SEK, and three of them had it in stock at the price check. This review is exclusively about the black variant with EAN 6959532328141. The same model is also available in violet under a separate EAN — Sexonic lists both side by side — so check the number if you compare prices between stores.

What Warren actually is: an anal plug that can’t slide in

The most important design detail on an anal toy is how it’s prevented from going in. The rectum pulls inward, and a sex toy without a wide enough base or without external anchoring is the only type that can become an emergency. Warren solves the problem differently from most plugs: instead of relying solely on a flanged base, the plug is fixed in a ring that sits around the penis and scrotum. The manufacturer describes it itself as a combined penis-and-scrotum ring with a securely attached vibro plug.

Practically speaking, that means two things. The first is that the anchoring is double — there’s both a wide, club-shaped base on the plug and an arm out to the ring. The second is that you can’t use the two parts separately. If you want just the plug, you still have to keep the ring hanging, and if you want just the ring, the plug stays attached. It’s a product with a single use, and you should know that before you buy it.

The shape of the plug is the classic prostate shape: an upward-curved, elongated body with a ridged top side, a narrower neck, and a wider ball just below. The manufacturer’s images show that the vibration motor sits in the bent tip. The base is wide and flattened, and that’s where the charging connector is located—marked DC on the manufacturer’s own image.

BI-040162W, MS0598-1 or 9935 — which number corresponds to what?

This product is listed under at least four different numbers in Swedish shops, and it’s worth figuring out which one is which before you compare.

• 6959532328141 — EAN, the global barcode. It’s the only number shared by all shops, and the only one that can be verified with the manufacturer.
• BI-040162W — the manufacturer’s own item number for Pretty Love. It’s the number under which the product appears in the manufacturer’s catalog, and that’s where the barcode is confirmed.
• MS0598-1 — Vuxenkul’s item number. A wholesaler item number, not the manufacturer’s.
• 9935 — Sexonics item number. The shop’s own, linked to black. The violet variant is under a different number and a different EAN.

It’s normal for shops to use their own numbers. The problem arises when you compare prices based on item number instead of EAN, because then two shops may appear to be selling different things even though they’re selling the same product—or vice versa.

Material and build quality: silicone all the way, but without a declaration

Material is the only characteristic of an intimate product that can’t be compensated for by experience or care, and it determines whether the product will still be hygienic a few years from now. For an anal sex toy, it carries even more weight than usual, because the lining of the rectum absorbs substances faster than normal skin, and because the product inevitably comes into contact with gut flora.

The manufacturer’s specifications field lists a single material: silicone. The packaging text goes one step further and states that the product is made from soft medical-grade silicone. This applies to both the plug and the ring—the entire product is the same molded piece, which is a real advantage over cheaper designs where a silicone part is joined to a hard-plastic shaft and the seam becomes a dirt pocket.

What silicone means in practice for an anal product

Silicone is a non-porous material. A non-porous surface can be cleaned, because there are no microscopic cavities where residue can be left behind. This is the single most important property of a material that will be in contact with mucous membrane. Softened PVC and the materials sold as “jelly rubber” or undefined TPE are the opposite: they are porous, they can’t be sterilized, and they break down from body heat and lubricants over time.

Silicone is also shape-stable. That means the angle of the plug against the body is the same every time, and on a prostate product the angle is the whole point—the prostate sits on the front wall of the rectum a few centimeters in, and a product that bends misses it. Warrens curve is firm, not adjustable, and it’s both a strength and a limitation: it sits where it sits, and if it doesn’t fit your anatomy, it can’t be adjusted.

The surface texture on the top side of the plug is ridged in the manufacturer’s images. Ridges on a silicone surface are harder to clean than a completely smooth surface, because residue can get stuck in the grooves. This isn’t an objection to the material, but it’s a reason to be careful when cleaning and to use a soft brush or your thumb in the grooves themselves.

Phthalates, BPA, and latex — a declaration that isn’t there

Phthalates are a group of plasticizers used to make plastic—especially soft PVC—flexible. The Swedish Chemicals Agency describes them as substances that can affect the hormone system and make reproduction more difficult, and several of them are therefore restricted or banned within the EU in a large number of products. This particular product category is repeatedly the subject of supervision because it contains soft plastic against skin and mucous membranes.

Pretty Love does not publish any declaration about phthalates, BPA, or latex for Warren, either in the specification fields on the product page or on the packaging. It shouldn’t be overinterpreted: silicone doesn’t need phthalate plasticizers to be soft—the softness comes from the polymer’s own structure—and the material specification “silicone” is, in itself, better information than almost any other detail in a product specification. But it’s still a difference compared with manufacturers that print it, and that difference belongs in a comparison. Anyone who needs an explicit latex statement for allergy reasons won’t get it here.

Dimensions: 170 millimeters total, 101 in the plug, and 44 in the ring

The manufacturer’s dimension drawing is unusually clear for the price range and provides four measurements. The total length from the top edge of the ring to the base of the plug is 170 millimeters. The plug part’s height is 101 millimeters. The greatest width of the plug is 29 millimeters. The ring’s inner diameter is 44 millimeters. The same four numbers are printed on the side of the packaging.

What can be determined from those figures is that the plug sits in the mid-range in terms of size. 29 millimeters in width—just under three centimeters—is more than a beginner plug but less than the bulkier models, and 101 millimeters is the total height of the plug part, not the insertion length. It’s an important difference: the manufacturer publishes no separate insertion length, and since the plug’s lower portion is a broad, flared base that is supposed to sit outside the body, the actual insertion part is shorter than 101 millimeters.

Here’s also the clearest example of how store data spreads and becomes wrong. Blush Me and SexleksakerOutlet list "length 10.1–17 cm" and "diameter 2.9 cm", which are the manufacturer’s 101, 170, and 29 millimeters converted to centimeters — it’s correct, but the interval format 10.1–17 suggests that the product would be adjustable in length, which it isn’t. Vuxen lists overall length 17 cm and the largest diameter 2.9 cm, which is correct. Vuxenkul, on the other hand, lists "diameter 4.4 cm" — and that’s the manufacturer’s ring measurement, not the plug’s. If you go by Vuxenkul’s numbers, you think you’re buying a significantly thicker plug than you actually are. The manufacturer’s drawing resolves the contradiction: 29 millimeters is the plug, 44 millimeters is the ring.

Weight: 90 grams, and why it’s low

The manufacturer states the net weight as 90 grams. It’s information that surprisingly many brands in this price range omit, and it’s useful for two reasons.

The first is that weight says something about what’s inside. 90 grams for a product that’s 17 centimeters long means that most of it is silicone and that the motor and the core are small. For comparison, Lelo lists 121 grams for Hugo 2, which is a considerably shorter product — 104 × 107 × 41 millimeters — and NS Novelties lists 288 grams for Renegade Apex. Warren is therefore clearly the lightest of the three, even though it’s the longest.

The second reason is practical. An anal product that’s carried at the same time as a penis ring hangs inside the body, and weight that hangs and is noticeable. At 90 grams, the construction is light enough that it doesn’t pull downward in the way a 288-gram product would. It’s one of the few points where Warren’s simple design is actually an advantage rather than a compromise.

Controls: two buttons on the product and one on the remote control

The interface is as simple as it can be. The manufacturer’s own button overview names two buttons on the product itself: one labeled ON/OFF and one labeled VIBRATION BUTTON. Both are on the underside of the arm between the plug and the ring, so on the part that lies against the perineum when the product is worn. The remote control is an oval plate with a single control button and the Pretty Love logo.

Placement is a trade-off. Having the buttons on the arm means you can reach them with your hand without pulling anything out, but it also means they lie against the body — and a button that lies against the body can be pressed in by mistake when you move. That’s the most likely explanation for why the manufacturer has added a memory function, which the packaging marks with its own icon: the product returns to the last used mode instead of starting over from zero.

Twelve modes or twenty-four? What the manufacturer actually writes

The number of units is the only point where the manufacturer’s own material is contradictory, and it deserves to be clarified because all Swedish shop texts have landed on one interpretation.

The specifications field on the manufacturer’s product page lists two separate entries: 12 vibration functions and 12 thumping functions. The front of the packaging likewise has two distinct markings — a box with "12 THUMPING SETTINGS" and an icon with "12 Vibration Modes". If you read the two as separate programs, it’s a total of twenty-four modes distributed across two stimulation methods.

The manufacturer’s ongoing product text says something else: it describes "12 different thumping and vibration modes", meaning twelve modes that mix both. All Swedish shops have followed that interpretation and write "12 vibrations- and pulsing modes". What actually applies cannot be determined from the material Pretty Love publishes, and the manufacturer publishes no manual that could clarify the matter. Expect twelve selectable programs as the lowest common denominator, and consider twenty-four as a possible but unconfirmed upper limit.

The difference between the two stimulation methods is, however, not semantic. Vibration is a motor that shakes; what the manufacturer calls thumping is a pulsing, thudding motion with a lower frequency and larger amplitude. The prostate responds, based on experience, better to pressure and rhythm than to high frequency, and for a product in this price range to offer both is unusual. It’s the single strongest line in the entire specification.

What the memory function does

The packaging lists Memory Function as one of four main features. The function means that the product remembers which mode was active when it was turned off and starts there the next time, instead of restarting from the first program.

On a product with twelve modes and a single mode button, it’s more valuable than it sounds. Without a memory function, you have to click through the entire list every time you turn it on, and on a product that’s already in place, every extra button press is a disruption. How many modes the memory saves, and whether it survives an uncharged battery, the manufacturer does not publish.

How is the Pretty Love Warren controlled remotely?

The remote control is included and, according to the manufacturer’s specification, is powered by an AAA battery. The manufacturer’s own image shows the battery compartment open with an alkaline AAA battery and a screw-on cover. That the battery is a standard type is an advantage — it can be replaced anywhere and costs nothing — but the cover is, at the same time, an opening in the housing, and an opening is always the weakest point when it comes to moisture.

Range, radio technology, and frequency are not published by the manufacturer, and none of the five stores provide any figures either. What can be determined is that the control is radio-based rather than app-controlled: there is no Bluetooth labeling, no app icon, and no reference to Pretty Loves app anywhere in the materials for this particular article. If you want app control and control over the internet, that’s a different product class—Lelo Hugo 2 has it; Warren doesn’t.

Vuxenkul lists three control methods for the product: buttons, wireless remote control, and manual use. The first two have coverage in the manufacturer’s materials. The third is the store’s way of saying that the product also works without power.

Penis ring: 44 millimeters, and the 20–30 minutes that apply

The ring part is half of the product that has a medical dimension, and it should be taken seriously. 1177 describes the principle outright: a penis ring makes the blood stay in the penis. The same source is equally clear about the limitation — a penis ring should not be used for more than 20 to 30 minutes. This is not a cautionary phrasing but a limit that’s about not shutting off blood circulation for longer periods of time.

That has a specific consequence for this particular product. Since the plug and the ring are connected, you can’t take the ring off and keep the plug. The time limit for the ring thus becomes the time limit for the entire product, regardless of how long you had intended to use the plug part. Anyone looking for a plug to wear for longer stretches should buy a plug, not this set.

Does 44 millimeters fit you?

The ring has one single measurement: 44 millimeters internal diameter according to the manufacturer’s drawing. That corresponds to a circumference of just under 14 centimeters when un-stretched, and since the silicone is elastic, the actual range is larger than the number suggests. But there’s only one size, and there’s no adjustment—no buckle, no locking mechanism, no drawstring.

The manufacturer describes the ring as a combined penis and testicle ring, meaning it’s intended to be pulled over both the penis and the testicles. The manufacturer’s drawing shows, at the same time, a single ring opening and publishes a single ring measurement, while Blush Me, SexleksakerOutlet, and Vuxen describe the product as a “double ring” with separate openings for the penis and the scrotum. Where the manufacturer and the stores contradict each other, the manufacturer carries more weight, and what you should expect is therefore a 44-millimeter ring that needs to fit everything it needs to fit.

Practically speaking, a fixed measurement means the fit is a matter of chance. A ring that’s too tight becomes painful and dangerous; a ring that’s too loose is of no use at all. The general advice that applies to all silicone rings is that they should be removable without difficulty in any position—if it sits so tightly that you can’t get it off, it shouldn’t be used.

Water resistance: what the manufacturer says, and what the stores write

This is the point where the difference between the manufacturer’s material and the Swedish store text is greatest, and it deserves a separate walkthrough.

Pretty Love does not publish any water-resistance rating for Warren. There is no IP rating on the product page, none on the packaging, and none in the specification fields. The closest the manufacturer comes is a sentence in the packaging’s introduction text: the product is USB-rechargeable "for fun in and out of the shower". It’s a piece of marketing wording, not a rating, and it says nothing about how long or to what depth the product can withstand water.

Blush Me, SexleksakerOutlet and Vuxen all three state outright that the product is vattentät. None of them provides a rating, and none of them refers to the manufacturer. So these are three store claims that go further than what the manufacturer itself says, and they should be read accordingly.

Why an IP rating matters — and what the absence means

The IP rating comes from the international standard IEC 60529, which defines types of protection for enclosures around electrical equipment. The second number in the designation indicates protection against water, and the difference between the levels is significant: splash protection is something completely different from protection against immersion. A product without a stated rating hasn’t been tested according to the standard — the absence of a rating is never a sign that the product is approved, only that no one has stated anything.

For Warren, that practically means: treat the plug as rinseable but not as bathable. Rinse it under running water, avoid submerging it, and be especially careful around the DC connector in the base — it’s an opening in the housing, and an unprotected charging contact is where water first gets in. The remote control should be kept completely dry, because it has a screw-on battery compartment and no rating at all.

Cleaning, lubricants, and storage

An anal product requires more careful cleaning than any other category. Rinse the plug in lukewarm water directly after use and wash with fragrance-free soap or a cleaning product intended for intimate products. Be extra thorough in the grooves on the top side and in the seam between the ball and the neck, where residue is most likely to be left behind. Dry it thoroughly and let it air-dry completely before putting the product away — silicone that’s stored while still damp can’t form mold, but the moisture can remain in the packaging and reach the electronics.

Use plenty of water-based lubricant. The anus does not produce its own fluid, which is the single most important difference compared with other use areas—and the reason too little lubricant is the most common cause of pain. Silicone-based lubricants should not be used on silicone products: they break down the surface over time and make it porous, and a porous surface can no longer be cleaned properly; just discard it. Oil-based products such as coconut oil leave a film that is difficult to remove and also break down latex condoms.

Store the product dry and separately. Silicone that stays against other silicone for a long time can make the surface become tacky, and Pretty Love does not include a storage pouch—according to the manufacturer’s images, the delivery consists of the product, the charging cable, and the remote control with battery, nothing more.

Battery and charging: USB cable, DC connector and three unknown

The manufacturer’s specification states the power supply as "USB rechargeable + 1 AAA battery". The breakdown is that the plug has a built-in rechargeable battery and that the remote control is powered by an AAA battery.

How do you charge Pretty Love Warren?

Charging takes place via a cable that the manufacturer’s own image shows in full: USB-A on one end and a thin, round connector on the other. That connector goes into the outlet labeled DC in the plug’s base. So it is not USB-C, and it is not magnetic charging.

The consequence is the same as with all products that have their own charging connector: if you lose the cable, no ordinary phone cable works, and the manufacturer does not sell replacement cables in the Swedish stores. On a product that costs 299 SEK, that’s not a disaster, but it is a real difference compared with a model that charges via USB-C—and it’s worth putting the cable in the packaging instead of the box with all the other cables.

The DC connector has another consequence too, and it ties in with the previous section. A hole in the silicone is the point where a product without an IP rating is most vulnerable. Rinse around the base, not over it, and let the connector dry before charging.

Run time, charging time, and capacity—three values that are not published

Here’s the specification’s clearest gap. Pretty Love does not publish the battery’s capacity in mAh, its voltage, the charging time, or the run time for Warren. None of the five Swedish stores fills in the gap either—they all just write "USB rechargeable".

It’s a bigger problem than it sounds, because runtime is the only figure that says something about how the product works in real life. The competitors publish it: Lelo lists 420 mAh and 3.7 volts for the Hugo 2, with up to one hour of runtime and up to two hours of charging time at 5.0 volts and 500 milliampere. Without corresponding figures for Warren, you can’t convert anything, can’t compare how heavily the cell is loaded, and can’t assess how many years the product can be expected to last.

What generally applies to lithium-ion batteries likely applies here as well: capacity drops with the number of charge cycles, the cell isn’t replaceable in a molded silicone body, and the product does best when it’s charged regularly rather than stored fully discharged. With normal use, it’s the battery—not the silicone—that sets the limit for lifespan.

The AAA battery in the remote control is, on the other hand, a clear advantage in this context. It’s replaceable, it costs a few kronor, and when the remote control stops working, it’s the first thing to try.

Pretty Love Warren compared with the alternatives

Two comparisons are relevant: against the premium alternative in the category and against a mid-priced alternative with similar technology. All information below comes from the respective manufacturer’s own specifications.

Against Lelo Hugo 2 — what a complete datasheet is worth

Lelo Hugo 2 is the product that shows what Warren doesn’t have. Lelo publishes dimensions of 104 × 107 × 41 millimeters, an insertable length of 72 millimeters, a weight of 121 grams, a lithium-ion battery of 420 mAh and 3.7 volts, charging time up to two hours at 5.0 volts and 500 milliampere, runtime up to one hour, sound level under 60 decibels, and a two-year warranty followed by a ten-year quality warranty. According to the manufacturer, the product is fully waterproof, is controlled via an app over Bluetooth, and has ten modes, six of which are accessed through the app.

Set it against Warren and the difference isn’t primarily in function but in openness. Warren also has a remote control; it has more modes and it has two stimulation methods instead of one. But on five of the points where Lelo presents a number—runtime, charging time, battery capacity, sound level, and warranty—Pretty Love presents nothing at all.

The differences in construction are also real. Hugo 2 is made to be worn without anchoring outside the body and has a broad base plus a perineum arm; it’s shorter and heavier. Warren doesn’t have a perineum arm in the same sense, but it does have the ring, and the ring does two things Hugo 2 doesn’t: it anchors against slipping in and it keeps blood in the penis. These are two completely different product concepts. If you choose based on the reported data and app control, Lelo wins. If you choose based on the combination of plug plus ring, and on price, Hugo 2 isn’t even in the discussion.

Against NS Novelties Renegade Apex — shockwave technology in a heavier body

Renegade Apex is in the midrange and is the closest technical relative, because it also combines motion with vibration and comes with a wireless remote control. NS Novelties lists the dimensions as 4.06 × 1.54 × 5.59 inches for the product itself and 1.1 × 1.54 × 3.15 inches for the remote control, the weight as 288 grams, the material as silicone, and the performance as six speeds and eight functions. The product is rechargeable.

Apex and Warren share the same weakness: neither of the two manufacturers publishes a water-resistance rating, operating time, charging time, or battery capacity, and both also lack insertable dimensions in the specifications. The difference is that NS Novelties lists six speeds and eight functions as two separate numbers, while Pretty Love lists two times twelve without explaining how they relate to each other.

On the body, the different products are different. Apex weighs 288 grams versus Warren’s 90, and it is a standalone massager bar with a perineum arm; Warren is a lightweight plug that is fastened to a penis ring. If you want a product that sits firmly under its own weight, choose Apex. If you want something that you wear while doing something else, choose Warren.

Price range: 299 to 609 SEK for the same barcode

Five Swedish shops sell the item with EAN 6959532328141. Cheapest are Blush Me and SexleksakerOutlet, both at 299 SEK. Most expensive is Sexonic at 609 SEK. So there’s a 310 SEK difference, or a 104 percent difference, between the cheapest and the most expensive shop for the exact same item, same color, and same packaging.

The stock situation is at least as important as the price spread. Three of the five shops had the product in stock at the price check: Blush Me and SexleksakerOutlet at 299 SEK, and Vuxen at 395 SEK. The two most expensive — Vuxenkul at 599 SEK and Sexonic at 609 SEK — were both sold out. That means the price spread you can actually buy at is 299 to 395 SEK, not 299 to 609. Shops that list a product as sold out may still have an old price in the feed, and that price is rarely what you end up paying when the item comes back in.

Two of the shops also list a regular price of 395 SEK versus their own 299, meaning the same level as Vuxen’s regular price. That suggests that 395 SEK is the level the item normally sits at and that 299 is a campaign level rather than a permanent low price.

The prices in the table above are updated when the shops’ product feeds are updated, but always check the final price at checkout. In this price range, shipping cost is a significant share of the total price: shipping of thirty to fifty kronor corresponds to over ten percent of the product value, and that can easily eat up the entire difference between 299 and 395 SEK.

Who is Pretty Love Warren for—and who isn’t?

It’s for you if you want to combine prostate stimulation with a penis ring, and want both pieces in one single product without having to assemble them yourself. It’s for you if you want a remote control—either so you can change the setting without fumbling, or so you can hand over the control to someone else. It’s for you if you want two stimulation modes—vibration and pulsing pressure—rather than just one. And it’s for you if you want to get into the category of cheap: 299 SEK is a fraction of what a Lelo Hugo 2 costs.

It’s not for you if you want to wear a plug for more than half an hour, because the ring is fixed in place, and 1177 sets the limit at 20 to 30 minutes for a penis ring. It’s not for you if you need to be able to use the two parts separately. It’s not for you if you want app control or control over the internet. It’s not for you if you require published information about operating time, charging time, battery capacity, and the water-resistance rating before buying, because Pretty Love doesn’t publish any of it. And it’s not for you if you need an explicit statement about phthalates, BPA, or latex, because no such declaration exists.

One more thing belongs in the decision. The ring comes in a single size—44 millimeters internal diameter—and it can’t be adjusted. So the fit is the single factor that determines whether the product gets used or ends up in the box, and you can’t assess it in advance based on the specifications. If you’re unsure about ring size, a separate adjustable ring plus a separate plug is a more forgiving way to get started—even if it costs more overall.

Safety: two things to know before the first time

The first one is about the ring. 1177 states that a penis ring should not be used for more than 20 to 30 minutes. If you get numbness, discoloration, or pain, remove the ring immediately. Since Warren’s ring is cast in silicone with no opening mechanism, it can only be pulled off—that’s why it should never be fitted so tightly that it can’t be taken off in all situations.

The second one is about the plug. Anal products should always have a broad base or an external anchoring point, and Warren has both: a flattened, club-shaped base and an arm that extends to the ring. Use plenty of water-based lubricant, start in the lowest setting, and take it slowly—the rectum’s outer sphincter can be controlled intentionally; the inner one can’t, and it needs time. If it hurts, the answer is always more lubricant and a slower pace—never more force.

If the product is shared between people, it should be cleaned thoroughly between each user, or used with a condom over the plug portion. Silicone can handle latex condoms without any problem—it's silicone-based lubricant, not the condom, that’s incompatible with the material.

Warranty, claims, and the right of withdrawal

Pretty Love does not publish any warranty period for Warren, either on the product page, on the packaging, or in any other material that the manufacturer makes available. That in itself is information worth having: with this product, there is no voluntary manufacturer warranty to rely on, unlike for example Lelo, which provides two years of warranty on the Hugo 2, followed by a ten-year quality warranty.

What applies instead are your statutory rights, and in practice they are more important here than with a product that comes with a manufacturer warranty. Under konsumentköplagen, you have a three-year right to complain about defects in the item, regardless of what the manufacturer promises or chooses not to promise. It is the shop you bought from that is responsible, not Pretty Love, and that responsibility cannot be waived.

For distance purchases, you also have a right of withdrawal for fourteen days under the lagen om distansavtal och avtal utanför affärslokaler. Be aware that, in practice, the right of withdrawal is limited for hygiene products that have been removed from a sealed package—but the right to complain about defects always applies. If you have questions about what applies in your case, Konsumentverket guides you via Hallå konsument.

A practical tip that follows from the lack of a warranty: save the receipt and the packaging. With a three-year right to complain and a product whose battery cannot be replaced, it’s the receipt that is your only leverage if the cell dies after one year, and the barcode on the packaging is what links your item to the store’s item number.
