The Throb Master Chamber Masturbator is intended to be a manual, single handed masturbation sleeve, or chamber, utilizing interior texture for stimulation and an air pump and valve for user control over their toy's tightness. The Throb master is not freestanding for use, but the exterior does provide some molded features for added grip.

This toy would be decent for someone interested in something that they can control the tightness of, though not very well. More on that later.

The main body of this toy is a molded plastic case that contains internal "noodles" for stimulation made of TPR. It does not have a strong smell right out of the box. The TPR "noodles" are attached to a plush ballooning tube on the inside which is intended to give extra stimulation.

The internal dimensions are strange on the Throb Master. It is only 6.5 inches deep. This may be okay for some, but others, I included, may hit the end while using it. And at first glance, it's available girth is huge. This is okay though, since this device is intended to be inflated, and inflate you can! This device can get so tight it's almost impossible to get in. That's right. Too tight. But it is easily adjusted on the fly to the tightness you need, making is suitable for even very thick guys. Not long, but thick.

This toy is larger than expected, so hiding and travel may be hampered unfortunately. Also, at first glance it looks like a penis pump, so even though people may not be able to guess what it really is, they might guess something else unwanted.

The mechanics of the Throb Master are great. you can easily inflate it, and deflate it, even while using it. That is the good. Unfortunately, the bad news is really bad. This toy is worthless. Its internals don't feel good, and it doesn't inflate evenly, meaning you have a pressure point on your penis, not to mention noodles trying to squeeze out of every nook and cranny.

This toy is noisy, in both masturbation and inflation. I also believe it would work fine in water, though it is hard to completely dry off afterward.

The Throb Master is tough to clean, since you have to remove the TPR sleeve and clean it with warm soapy water, let it dry, then reinsert it into the plastic holder.

I would also recommend water based lubes with this toy.

This toy is not stimulating and not worth purchasing again. If you really want something that is tight, go for it, that it is, but stimulating it is not.
