Successfully fixed rings for CB6000s knockoff

The main distinction between a genuine cb6ks and the cheaper knockoffs (commonly found on eBay) is that the authentic model features a smooth ring. In contrast, the fake version has an irritating ridge that digs into your scrotum. I used a lighter to melt the plastic flat—just make sure you wear a mask or some kind of protection against fumes while doing this—and once it cooled, the surface became quite even. As another tip, I also applied heat where the two halves of the cage connect to reinforce that area. Be careful not to scorch the plastic; I’m uncertain whether burnt plastic remains harmful after cooling down.
