CB Range discussion

I was cycling to the office today when I felt that infamous pinching sensation from a cracking CB cage. In my panic, I managed to extract the piece of skin caught in the seam, with help from my penis going soft due to the pain. Once at work, I wrapped it up with electrical tape to prevent further skin pinching. I got back home and superglued the bottom seam, just as I had done earlier with the top one. My main complaint about CB is that they should eliminate the seam entirely in future versions of the product. Don’t you think? The edge is quite sharp and capable of cutting into the penis. I hate to think what would happen if I were in a car crash while wearing this thing. I’m now looking for an alternative chastity device, as this will be my last CB purchase.
