Master Series Penis and Testicle Crusher | Adjustable Acrylic Cock & Ball Board for Intense Pressure Play | Secure Wingnut Control for Custom Fit | MO106 | 7 in Length | Durable & Body-Safe

When I saw my first CBT video, especially with the many homemade crushers used in the video, I tried to make my own! Wood was too thin, and skin kept getting caught in the screw threads, not a good feeling! Then I happened on a video that this same type crusher was used , and began my research for this. Looking through many online CBT stores, I finally found this crusher that was in the video, but the prices were sky high! I never knew Amazon even carried any type of Adult Toys, let alone anything for CBT! This one was reasonably priced, compared to some of the similar ones that are higher priced. Amazon even has one at a higher price, but they look the same! Now I can enjoy CBT and crushing without pinching the skin like I was doing with my feeble homemade version! Caution; You can still pinch your skin on the threads and the Acrylic top piece but a little maneuvering you can keep that from happening, unless you are into some pain along with crushing, but having your skin caught in the threads and top, takes all the fun of what you are really trying to do! Once you get this comfortably tight and add vibrations from vibrating male or female toys or bullets, you are UP for one heck of an experience! I even spiced it up a bit by adding a small ring around my scrotum, but that is when your skin gets pinched on the threads as you tighten down the the crusher, unless you do some minor adjustments to your scrotum!

I was very disappointed in this crusher. The 2.25" base hole is way too large for the average man. My testicles tend to want to slip out. To me, the base hole should fit like a cock ring. The average man probably wears a 1-3/4" ring to at most a 2" ring, making 2-1/4" way too large! I wear a 1-7/8" ring. The knobs on the device I received were round, not the straight ones shown in the product image. They've also changed the design from what's shown in the photo. It no longer uses the hinge that's shown. The hinge is molded into upper and lower pieces of plastic with a pin inserted to hold them together. With the new design, I suspect the plates sit further apart or "higher". Because of that, when tightened, the upper plate will go below horizontal or "parallel" to the lower plate. My testicles are by no means "tiny", so if it's happening to me, it's definitely happening to others. When tightened like this, as the plate dips below parallel, it pulls the testicles toward the opening, making them even more prone to want to slip back through the oversized opening towards the body. I wouldn't recommend purchasing this crusher at all. What you're seeing is not at all what you're getting. And the posted advice about the size of the holes not making any difference once it's tightened (assuming you can get them to stay in place to tighten it), particularly in regards to the 2-1/4" base hole, is not at all accurate.

I've never understood why companies and customers never give better descriptions or reviews, but hopefully this one is helpful.The attached pictures show the opening sizes in inches (2" rear and 1 1/2" up front). Both holes are rounded and smooth. The plastic is a good thickness, the top plastic hinge uses no screws. The compression screw knobs turn easily with no tightness or catching.I really am glad I bought this Master Series instead of some other CBT press. I just wish they'd design these with an L shape piece of plastic so both pieces lie flat against each other when fully closed. But otherwise, I'm pretty happy with this one.

It's an incredibly simple device, so let's talk about build quality: The edges of the plastic are nice and smooth, the hinge is well-made and attached securely. The knobs are a bit cheap, but they do have a metal washer in them for longevity's sake. I find it hard to get into, but once in, it's a bunch of fun! The only concern I have is if you're a bit on the thicker side, and you're in it, and you're aroused, it's not easy to get out of. So, be careful in that regard.

I started to go to find some clear plastic material to make my own to start with but it was too convenient to just order this one without having to spend all the time. But, if you notice the hinged side on this one leaves quite a large gap in the back, preventing the top from achieving its full crush potential. Not only that but the angle the top comes down due to the jacked up hinge wants to push the balls back towards the non crush side. So I wound up having to cut the original hinge off, go to the hardware and buy my own. Now the pinch point is from the back forward and you can get it as tight as you have the "balls" to tighten it. If this one breaks, I'll make my own next time. But hey, the wife sure has a big smile every time she turns the screw and that's worth 40 bucks and a little time right there.

Wonderful little toy. Its simple enough and I agree that the plastic can break but really just go slowly and turn one side at a time. Its a lot of fun seeing the little guys squished and it certainly gets your attention. Its reasonably large so you can put all of the 'jewels' in one go for a little extra fun.If you like things a little more exotic heres an idea that she likes to do - cut out some small rectangles of plastic carpet protector top and bottom of the acrylic side and pop the little guys in the sandwich! Slowly does it, it makes for a fun sensation with the small plastic spikes providing and extra level plus no need to tighten very tightly so there much less strain on the device. Play safe and have fun :)Something like this works wonderfully. https://www.amazon.com/Multi-Grip-Deep-Pile-Carpet-Protector/dp/B001713P58

I am newer to CBT and so didn’t want to break the bank. This item in theory was cool. However I am not huge and it cuts off circulation to staff, and used once, not even that tight and it developed two cracks. One and done for me, item was trashed. Hope this helps someone else.
