With a name like "Jack Master" your expectations are high. However, this toy was difficult to truly master, and other companies have improved upon the many design flaws with this toy. If you don't mind your balls being pinched in plastic while masturbating, you may like this toy. I, however, will be looking for a new Master.

This is not your father's masturbation sleeve. The Jack Master is truly from the future, created with you in mind. I never thought this sort of sensation was possible. All I can say is that the name says it all, it definitely is a "Jack Master."

The Jack Master is an innovative design with multiple textures, a flexible, squeezable exterior and an easy clean TPR interior. Unfortunately, faulty hinges/closure tabs made it nearly useless for us as it would not stay closed.

The Jack Master is the best masturbation sleeve I've used so far. It's a little heavy and hard to hide, but why bother when it looks like something you'd stick your action figures in? And yes, this one actually does come close to 'the real deal'.

This is a good product if you can look past its flaws. It has a learning curve that's unusual, and it leaks frequently. Overall though, it beats using your hand.

The Jack Master is great for getting the job done. While it's not "better than the real thing", it's pretty close, and pretty good. We found it a good supplement to a hand job and blow job, as well as for solo sessions. We did experience some technical difficulties when the case would pop open during use, and would have preferred it to be a little less bulky and heavy. Nonetheless, Jack Master was enjoyable to use and we will be using it again.

This is a great discreet masturbator that cleans easily. The design is fun and the nubs offer a pleasurable sensation during use.
