I’ve tried other rings, but the Power Flex is the best for me so far. It’s also the only one that I can wear comfortably the whole day. I’ve ordered the 45mm, which is just right and nicely lifts up my package…but I think the 40mm (which I’m buying now), would be a better one to use during playtime with my wife. Totally recommended!

I ordered a 50mm Power Flex (based on the round rings I've used) and found it just big enough to fall off.
The 45mm is just right.
All the best to everyone at Primal.
I'm interested in getting a number of the smaller ones for stacking.

Really nice fit for daytime wearing, wife is very happy with the look under clothes as well as without.

Have now this ring and the metal ring , both fit well , and the process of buying is super..cannot recommend these guys enough !! Thanks kev

I'm obsessed with Primal rings... I already owned a metal Primal ring prior to purchasing this one and use it everyday so when I saw that they came out with a silicone one I immediately had to get both of the new models. The Power Flex ring is by far my most favorite. The contour shape and fit makes it so comfortable for extended wear (when flaccid) to the point that I sometimes forget that I have it on throughout the day. Not to mention, the wider and flared edges on the Power Flex really pull my package up and out at the base giving it more support and making my bulge more prominent looking. When erect, it fits nice and snug keeping the blood flowing to my penis making it rock hard and my veins throbbing. Also, it's tight and comfy enough to keep a semi when I'm edging during my solo/bate sessions. The silicone material definitely makes it easier for quick removal. This ring is overall a winner and I highly recommend it.

Lastly, S/O to the team at Primal Rings for your stellar customer service. My order was received quick and the personalized note in my package was a nice touch. I'm a customer forever. Thanks!
