This is an absolute gem, I got the 55mm, which fits perfect and tight. I have other Primal Rings 50 and 45mm but you know this is sometimes trial and error. I cannot put the 50mm. If custom or small steps on size would be available I would go for a 53mm.
Now, the 55mm is a beauty, my wife loves it and she thinks is so sexy, besides, when I put it I can feel an inmediate sense of pleasure down there, so it gets half erected which is nice. It keeps the erection harder and longer and the orgasms are also longer, I cannot see having sex without it is just better sex!!
Keep up the good work and hopefully small steps on size are available so I buy another one slighly smaller!

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.
