Love how it fits and stays in place to wear all day under my Calvin's

This is the first ring I have ever bought and it is great.

I have a Fusion in brushed stainless and polished stainless Energy, both in 45mm. I love both and use them frequently for solo or lovemaking sessions. They press on my prostate in the most amazing way, are never uncomfortable and are the perfect size for keeping me at 125% max hardness.

I frequent this site in case anything new pops up. When I saw you added silicone rings, I knew I had to add one to my own collection. This truly is an all-day ring. It is soft, flexible, COMFORTABLE and stays on without having to hike it up like the smooth, heavy metal models. (I once wore the Fusion to a grocery store under shorts, commando. As I was bagging groceries, the ring slipped off and bounced off the concrete floor with a loud TINGGGG! Luckily it bounced straight up and I caught it with an open hand and slid it in my pocket with nobody noticing what it was!).
I plan to give it the bedroom test drive very soon but I am confident it will be an amazing device for adding hardness and increasing the pleasure of orgasm just like my Fusion and Energy.

I agree with many other reviewers that recommend going down a size from your regular Primal size. Throw your pride out the window, guys, and order a size down! 40mm fits me much like the 45mm metal models. Any larger and it would easily slide off. I was hoping that ordering down a size would give a tighter squeeze and really hold that blood in, but in reality it is a much more comfortable yet similar fit to my 45mm rings. I do highly recommend the thicker Power Flex as it pushes your goods out front and center, and is so comfortable that it truly does not feel like you are wearing a ring ( I am at a standing desk wearing this ring and it hasn't moved all day. It will get the HIIT workout test shortly).

Primal is the ONLY Ring company as far as I am concerned. The Silicone collection is another home run and it would be nice to see some fun colors added to the mix.

I’ve had the ring for about two weeks and have enjoyed it often. I like the width of it but I find I can still wear it for longer periods of time. Lots of fun. Thanks for this option!

This ring is very nice. I have the Tantus 2" silicone ring, but this is more comfortable for longer use. Doesn't pinch, but I know that it's there. Very fun!
