I was skeptical of using such a device but its design is what convinced me to give it a try. Based on my measurements I was concerned the 55 mm would be too small but as it turns out it was a perfect fit. Being SS it has some weight, the smooth surface aids installation. Very impressed with the outcome for which it was designed.

After trying the 50mm which was definitely too big, I did decide to try the 45mm and I am pretty happy with the decision. It can be a bit tight at times and I wish there was an option for a size in between which would be a perfect fit for me (i.e. 47.5mm). The quality is fantastic as was the other one. I recommend if people are unsure on sizing or in-between sizes to definitely get the smaller one. If there was additional sizing options, I would definitely purchase more.

This is the most comfortable metal ring I have ever used no doubt!
Great for performance and comfort.
If you are looking for a new ring look no further!

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.,
