So this is a fairly dang good cage I think. I like the fact that there is enough room in front to get your foreskin out of the bars in front, but like most cages, it's not enough room to be comfortable for the foreskin. I like the curved ring, I'm personally a big fan of those for comfort.
BUT, it comes down to the fact that even with the right size ring (45mm, it's the right size for the other cages I've tried), it hangs way too low. Not sure why, I guess the gap between the tube and ring is too big.
So IF YOU ARE LOOKING TO BUY THIS CAGE, HERE IS WHO SHOULD GET IT:
You are circumcised, your flaccid length is less than 3.5 inches, and your flaccid girth is less than 1.5", and you have higher resting balls.
You aren't circumcised, and your flaccid length is less than 2.75 inches, and your flaccid girth is less than 1.5", and you have higher resting balls.
Hope this helps.
