After my first Black Spark 50mm ordered in 2022, I puchased a
in 2023 a Fusion in 45mm which I have been using 24/7 with excelent confort in all the situations. One year later I decided to try a 45mm Energy that I received last week and...wow!!!
Probably because de extra thickness, it fits just a little bit tight compared with the Fusion (maybe 47.5 would be the perfect size) but in any case absolutely confortable. When flaccid, all remains in perfect place and confort all day even in movement, no marks, no slip off, no surprises. When erected, I really note Energy is there: harder, thicker and longer performance assured.
Quality is fantastic and seems that the mirror effect will remain with no problem long time.
Excellent customer service and fast delivery.
Go ahead and try this incredible ring!!!.

This is the only metal cock ring I've ever been able to wear and keep on comfortably. I was skeptical that these would do the trick as I've tried them all, snap on, silicon, magnetic, steel embedded in silicon. Not only do I not have issues keeping it on, it doesn't feel like it's cutting off circulation like silicone ones can or that I'm not going to be able to get it off when I'm hard.

The ring fits perfectly around my junk. Love the look of the stainless. When erect I can feel the sensation fighting around my shaft. Results in longer harder erections. My partners love it too. I wear mine 24/7 with no issues. Only wish I had purchased it sooner.

Had previously purchased a 45mm Pulse Flex which is a super CR. Then Purchased Energy in 45mm. The fit is much tighter, but results in rock hard results. It is somewhat difficult to get on and I should have gone for the 50mm. I have now ordered a 50mm for a better fit. These CRs are " WOW."

I really like how comfortable they are but wish it was a bit heaver. I have an old ergonomic cock ring from another company I purchased a few years back the comfort is equal but it weights more! I like the feel of the heavy on better.
