This item definitely surprised me!

This is a stretchy cock ring with a removable, battery powered bullet stimulator. The bullet is situated over your clitoris.
The ring was stretchy and not too clingy. It fit well for my husband (who has some very large equipment). I would say this is a one size fits most product. I like that once we got going I didn't even notice the rubbery texture of the ring and bullet. The texture on the bullet is enough to stimulate without rubbing you raw. Just make sure the texture is facing the right direction! I'm sure you could also flip this around and use it for back door stimulation too (this same company makes a double bullet ring, too, fyi).

The bullet has 3 settings: off, pulse, and vibrate.
The vibrations are strong compared to some single small bullets. I enjoy the vibrate feature more then the pulse, but that's a preference. I really like that it's quiet and doesn't make that rattling type of sound. This enables me to slip it on one of my toys if the husband isn't around. The cock ring serves its function of delaying your man. The most difficult, and funniest, part about this ring is trying to take it off when you're finished. The bullet button is on the side of the bullet and it can be difficult to turn it off if you're both exhausted. But this can also be infuriatingly fun!

It can be used with lube and is very easy to clean. We use soap and water. The bullet is also removable for extra cleaning or to change the batteries out.

The ring is an amazing enhancement to normal sex and doesn't get in the way if you want to incorporate more toys into the fun.
