The Jack Master started out being a really cool assignment for us. It's red, it's hinged plastic, it's squishy TPR inside with multiple textures. You can open it up to clean it and squeeze it to make it super tight.

But that, right there, is where the good stuff ends for us.

Our Jack Master ended up being a Flop Master. As in it flops open at the hinges every few strokes and makes actually jacking off with it impossible.

But let's start at the beginning, shall we?

The Jack Master is a male masturbator. It comes packaged in a cardboard box with a picture of the toy on the outside as well as text stating it was "just voted #1 masturbator by the American Pumpers Association" and that it's "better than the real thing" and "you're in control!"

Ours is red plastic on the exterior that is hinged, so it opens for cleaning. It has a removable cover over the opening and sides that are flexible and can be squeezed or gripped for control of how tight the chamber is.

The inner chamber, which is accessed by opening the product lengthwise along it's hinged exterior, is dual sided, with different ridges and tinglers/nubs on each side. It is made of clear, gel like TPR that is soft and squishy.

The whole toy is 7 inches long by 3.25 wide with the interior being 6 inches in depth by 1.5 inches in width, according to the site specs. That may be true of the insertion hole but the inner chamber is much wider than 1.5 inches. In use, it felt quite unstimulating and had to be squeezed very tightly for the texture to be felt.

It's also quite heavy. The shipping weight is 1.5 pounds and it's very unwieldy in use, heavy and tiring on the arm.

The light/slight sensation and weight would probably have been tolerable, however, if it hadn't been quite defective in it's hinges. Not the hinges themselves but the tabbed area on the other side, where it opens and closes. It simply would not stay closed.

Which, in use, made it seem rather like a chomping shark trying to bite off my partner's willy. Every few strokes it would either fly open completely if he wasn't gripping it tight or it would open a bit and close, like it was crazily chompchompchomping.

We may have just gotten a faulty toy but, regardless, this one was a fail for us.

It is easy to clean; just open it up and wash the TPR interior and plastic exterior under running water with some soap or toy cleaner.

Storage is nice, too, as you can close it up, place the handy cover on the entrance hole and tuck it away without it getting all dirty inside.

But the chomping...

I'm going to say this one will likely get tossed well before it gathers dust.

The Jack Master Chomp Chomp did, indeed, end up thrown away. It's a toy that's gotten really good reviews -- other than the fact that the hinges just don't want to stay closed. Even on those that seem solid at first, reports are coming in that they weaken with use.

We did try this a few more times, just to give it a shot, but having to hold it closed and inevitably have it chomping open and closed when the hand got tired just made it not worth it.

A good effort, good idea, but I'd say stick with the Tenga Flipholes. The quality is much, much better.
