It’s excellent!
It great, the o ring is cheap though which was a plus for me. It’s just soldered and I was able to pop it off with large gauge ring opening pliers, and modify to make a Mugler star pendant out of it. The collar itself is perfect. Yes the screw is very small, but just loosen slowly and let it open and you won’t loose it. The screw actually sits flush when screwed down. The other point people seem to be hung up on, how does 130mm=16in? 130mm is the inner diameter and 16in is the circumference. I have a 16 in circumference neck and the 130mm option is fitted with a comfortable amount of space so it doesn’t choke.
