This is my first foray into steel but, after I tried the Fusion in silicone, I was ready. It's so comfortable that it's easy to forget it's on when you're not hard. Once you're hard, it's like having a new body part. Love it.,

At first I bought a 45mm ring but it was too loose so I decided to step down to a 40mm one. I would say that this smaller ring is a beast, maybe too tight, it hurts after some action, it is on the limit. I would love to see half step sizes 40- 42,5- 45- 47,5- 50- 52,5, etc... a 42,5mm one would fit me 100%. Anyway, I love my rings, they are awesome and beautyful

Maybe next time I'll purchase one (1) size.smaller

This piece is phenomenal. The feel is beyond comfortable . The aesthetics are top notch and the performance is lights out . Keeping the pipe extremely full . Had a girl say it was too hard , nuff said
I’ll take that complaint all day with pleasure.

I had tried other c-rings before, but they never quite felt comfortable, so this design had me hopeful. I measured multiple times to be sure and seemed to fall on the cusp of 40 and 45, it seemed to be recommended to size down, so I ended up getting the fusion, pulse, and power in 40. Packaging and quality of the rings seem great, but I don't know if it's too small or my anatomy just doesn't work with it, but I couldn't get both testicles through with any of them. Debating if I want to give it one more try with 45, but worried that c-rings just don't work for me.
