This is a pretty standard masturbation sleeve. Has a hole at one end and a set of four ribs that spiraled up the shaft. The 3D Tornado Hole was very easy to hold at about 6 inches before stretching, and felt phenomenal. Felt great to use by yourself, but I'm sure it'd be even better with a partner.

The material was a very realistic feeling cyberskin. It was soft and supple with no smell. I did notice it had a tendency to suck up lube and had to reapply a couple of times during use. The ridges on the inside felt phenomenal and created a great suction.

The shape of this was pretty basic for a masturbation sleeve. It fit very well in the palm of my hand. This toy was very easy to grip and hold on to for stroking. At six to seven inches, the size of this toy was almost perfect for my cock, but still small enough that it would easily be hidden or fit in a suitcase. A great size and shape for travel. I should mention it fit wonderfully, but in the end wasn't stretchy enough and I broke through the end. Definitely wouldn't recommend for anybody of above average length.

There were no real "functions" to mention with this sleeve other than the ridges that made an excellent sucking sensation. It was fairly quiet and felt almost as good as the real thing. The internal texture was very stimulating.

Well since the end broke and shoved all the lube out of the rupture, the cleanup was pretty simple: I dropped it in the trash. If it hadn't broken I would say soapy water and/or toy cleaner would do the trick pretty well. I'd also give a light dusting of corn starch before storage to keep it feeling soft and not sticky. Also as cyberskin is silicone based, I would keep it in a plastic bag separated from other toys. ONLY use water based lube with this toy.

The package consisted of a box full of Japanese writing and a nekkid Hentai babe. Can't tell you much more based on the fact that I don't really know Japanese. Also came with a little tube of lube, which after using may have been silicone based. Never used silicone before so not sure, but was rather thick and viscous. This may have led to the breakage.

I was really loving this toy up until the second it broke, and then it still felt good for a bit, but pushed all the lube out of the rupture and lost all the suction. The fact that the 3D Tornado Hole felt mind-blowingly good-it felt extremely realistic and didn't take much imagination for it to be my wife riding on top of me when I closed my eyes-made it even more disappointing when this toy broke.

If it would have survived the first session, it probably would have become a staple of my "happy fun time" sessions, but alas it didn't make it through the "hole" session and left me high and dry and turning back to one of my old toys for relief.

The experience went from incredible highs of pleasure to extreme lows of disappointment after I broke through the end cap. It was phenomenal, but didn't do anything after it broke.
