First and foremost, I like my CherryKeepers. I have four of them and like 5 rings. I also own and tried like 25 other cages, metall and plastic, but the CK is the most used one. The Pros: They are light and don't pull you down. You can choose between a huge amount of designs, one of them should fit you. Being uncut, I love the no-touch designs. Meant as no touch - you cannot touch your KH best piece, it's like in full armor. But the big benefit is also no squeezing of skin. This way you can ride your bike / motorcycle and do other sports without the risk of skin getting between your cage and underwear and is pulled/stretched/squeezed and gives you (unwanted) pain. Through the many designs available its also a great way to test the sizes you need, before you invest in a custom made steel one. They are not cheap - compared to many chinese ones. You have to add the ring and shipping and taxes to the price in the shop, but they are not that expensive also. Before getting a CK, maybe try some Chinese ones, delivered with many rings, so you dont loose to much money trying the wrong ones. Invest in a set of sandpaper / polishpaper from amazon / ebay .. to polish out the grains. If you wake up at night, vaseline / coconut oil (available without the coconut smell) / Ball Wax from Dick Johnson may help you (apply genorously to scrotum before going to sleep). Another option would be to get a "sleep cage", wider and longer = better sleep. When I go smaller, it only gets worse. The Cons: The big one is the gap / height difference between the A-ring and the cage. It's like 3mm, but many of you know, in this area every mm counts. It prevents a tight fit and makes pullout attempts much easier than they should be - combined with the sock technique its really easy. With 3D printing techniques and concept it should not be that hard to remove that gap and add some additional printing material to the ring to avoid that gap - either the whole way between cage and lower the ring to a straight line or at least lowering the ring. Better fit and more secure. According to the designer the male penis looks like see the attached pic. If you take a look down below on yourself, you might notice, thats not the real thing . If possible, please fix this issue with some brain juice - Id be happy to try out improvements. A minor one, not directly related to the CK-system itselft is the shop. You cannot see on first sight the specifications and most important sizes (width / length), you have be patient and click through them and find the differences between the different cages by yourself. A more structured navigation system would help a lot.
