Size. If the toy is meant to be inserted, size is the easiest thing to get wrong. What looks like the right size in a picture is often bigger in real life, and a toy that’s too large will just sit there. Choose something smaller than you think, read the manufacturer’s measurements in millimeters, and feel free to compare it with something you already have. More about it in the guide What size dildo?For external sex toys, size matters less, but the fit does — Womanizer solves it for Premium 2 by including two stimulation tips in sizes S and M.
Material. Choose body-friendly silicone, glass, or metal. They are non-porous and can be cleaned properly. Several manufacturers declare that their silicone is free from phthalates, BPA, and latex — for example, We-Vibe and Womanizer do this for the models below. More about the materials in the guide "safe materials in sex toys.
Water resistance. A toy with IPX7 can be submerged for one meter for 30 minutes according to the IEC 60529 standard, which makes it easy to clean and possible to use in the shower. It’s a simple quality marker to look for.
Warranty and charging. A toy with a longer warranty and a charging cable that’s easy to replace is a better gift than one that stops working after a few months. Most toys come with a product-specific magnet cable — that’s normal, but it’s a good idea to mention it so the cable isn’t thrown away with the packaging.
