This toy, is very obviously best used as an aid to stimulation during the act of coitus. It can be used by anyone with a penis or penis reminiscent object as an added bonus during thrusts. It should work for all but the most desensitized people who've been around so long it takes a belt sander for them to get an erection.

The material is great, the only cock ring I own that doesn't pinch or prod or squeeze too tightly. The material is smooth, has no off putting smells or tastes and feels like a dream. The material is TPR and as such maintains a very high level of elasticity, though it could break if you were trying to stretch it around say... a bowling ball? The texture makes the ring feel like it's not really even there, which is fantastic during intercourse. I wouldn't say the texture was stimulating in and of itself but there's no doubt in my mind that it get's the job done.

It's a butterfly with over sized antennae that are supposed to tickle your lover's inner regions. The butterfly is sort of perched above a vibrating bullet about the size of... half a key? A thrice broken pencil? 2/3rd's of a Triple A battery... It's small, maybe an inch and a half with a quarter inch diameter. No special attachments needed since it kind of is one, I thought the bright blue butterfly floating at the base of my shaft was a little disconcerting, I'd prefer something a little more manly like a tiger or a dragon or a Shelby Mustang. There's really no way to adjust since it will fit anything larger than an 6/8's of an inch around and is really easy to put on or take off. I wore it to work and at times forget it was there, until it started buzzing because I had inadvertently triggered the on switch. The switch itself is a small raised projection on one end of the bullet that can be slid forward to turn it on.

It vibrates with an intensity that I felt was fairly high, though it did it quietly and without much of a fuss. In a quiet room it could easily be heard through pants but with just a bit of conversation or background music I doubt anyone would notice it all. I enjoyed it handily and use it often just to masturbate with.

TPR can be cleaned with hot soapy water, and should be cleaned often since it is a semi porous material capable of picking up and spreading all kinds of nasty stuff. Though with this toy it would be better to use it over a condom and just make sure to clean it after each use.

I noticed that if left on for an extended period of time, between ten and fifteen minutes the batteries act like they are dying down and don't want to really work anymore. After turning it off for a few seconds and then turning it back on the vibrations resumed just as powerful as when I first turned it on.
