Enjoyed it (after an initial mishap)

From AlleyKat

This was the very first stroker I ever tried in my life, so I mistakenly inserted myself in between the sleeve and the plastic casing, and thought this was rubbish, since I was rubbing against a rough sponge and the outside of the sleeve :facepalm: Then pulled out and realised oops, I was in the wrong hole, so more careful inserted in the right place, and it was a very nice and soft feeling, and soon afterwards the job was done. It was a pretty good sensation from the moment I fixed my mistake. I'm personally uncomfortable with the waste of plastic and other materials per each use, and $15 per masturbation session can get pretty expensive, but if you wanna try out sleeves and see if they're your thing, I tried four different Tenga sleeves and this one's my favourite of the single-use ones so far. (You're not supposed to reuse it like some other commenters here seem to have done. Throw it away after use. There are other reusable sleeves by Tenga).

It doesn't deserve a star.

I bought two strokers. This one was interesting for the name. I threw it out after using it twice. Follow your gut feelings, I should have on this item. My bad. Lesson learned. Naughty boys is the best website I have found. Best choices, best price and best service. They delivered items very fast.
