I noticed there aren't many people reveiwing this product so I wanted to add my opinion. I have had this toy for about 8 years and it certainly is not one that I use often. At first it was a struggle to get it in my butt and it hurt a bit as well as giving me uncontrollable sensations that I can't describe except that my ass was saying ^get this thing out of me!^ but that's the idea right? Because the shape of the hand and wrist is very similar to a butt plug, it stays inplace. so then taking it out became just as painful as putting it in, but you know what ? I can use it now without pain because I am more flexible down there and I use a lot more lube than before, Do not skimp on the lube. I am a person of average build so this about as big as I can go. The surface is smooth and the price is right for those wanting to go to your limits.
