Well, the toy is free standing sleeve. There are no motors or tricks, just a sleeve of UR3 material. I would wholly suggest a modest amount of lube (water-based only!) for good effect or else you'll feel the burn baby!! The best use for this toy is for when you don't have someone to give you a little. With the textured inside, (lots of nubs) you get to decide how tight you want it. Depending on where and how much pressure you apply, it will stimulate the head or the shaft. If you are going to share your toys, I suggest a condom for safe sex!

UR3 material is hypo-allergenic and phthlates- free, smelled odd but what the hell, you're going to stick your dick in it so what do you think its going to smell like afterward? It's very soft, pliable, and when used vigorously there were no splits or rips in me or it!

Interesting to find opaque lips on one end and a hole on the other. Worked as advertised, just a quick way to make masturbation, a bit different. Good fit for most men, gives a bit for the larger and with a bit of squeeze it will work for less than average.

Hey, no mechanics here. Just your hand and the sleeve. Maybe warming up the old arm and hand before vigorous activities will help with any soreness... but hell, if you are getting a sore hand/arm from this... shouldn't you be seeing someone professionally?

Recommendations: UR3 is extremely porous, and should be cleaned between each use with warm water and soap or anti-bacterial sex toy cleaner. Cornstarch and a soft cloth can be used to bring the toy back to life after each cleaning. Storage: storage bag or wrapped in a thin material due to porous nature of material it can absorb anything that comes in contact with it.

Want some sucking sounds? Apply more lube and it will "talk" to you!

Wife thought it was hot as hell when hubby worked one out with it under her supervision. She even gave a hand!
