I got a CB6000 a little while ago, and had the same problem described in this thread: http://www.chastitymansion.com/forum/showthread.php?t=421 Basically, the two halves of the cage come apart slightly, and can cause abnormal pinching resulting in severe pain. I contacted the manufacturer, and they sent me a new cage. However, after a little teasing, my erection caused the new cage to split as well. This time the whole thing came apart. I contacted the manufacturer again, and they sent me a 2nd replacement cage (3rd cage in all), and the exact same problem happened again. My understanding is that these things are supposed to stand up to this kind of treatment (i.e. lots of pressure due to cock trying to get erect). Am I missing something or doing something wrong?
