- The ones that say they are stainless steel really are! In fact the three I bought are not attracted to a magnet. This is a sign of good stainless.
- They are well made. Without exception each device is welded cleanly and finished with a nice smooth buffing. The parts fit together well and the gap for the scrotum is very nice, at least for me.
- They are effective. The cage I am wearing has a solid metal plate that extends the length of the shaft on the bottom. It effectively covers those nice sensitive spots under the head. The gap in the head cage is well placed for fairly trouble free peeing.
- It's easy to put on and take off for the keyholder. I don't think I could pull out on my own (I won't try) and if I do, I am sure I couldn't get back in. I have a correctly sized cock ring 1 3/4".
The best part is that for less than $50 I have a stainless steel cage that is a good fit. I don't have to deal with the problems that plastic or silicone cause. I needed to buy two to get the right fit, but still that is less than the cost of one CB6000 (from the US maker). While this isn't going to be as perfect as a custom made Jail Bird, I have no pain wearing this and I sleep through the night without being bothered. I think that is pretty good.
