I have waffled on wearing a ring as my past experiences have been very uncomfortable. The spark is a total game changer; I bought the 50mm based on measurement and it’s a perfect fit. Tight but not too tight, and loose enough when soft that I can wear it all day. Exactly what I was looking for. I may opt for a 2nd smaller gauge one now that my confidence is restored in the existence of comfy and effective cock rings.

I was looking for something incognito and I found it.

The black spark hides in my pubes and gives me the best erections I've ever had in My life. And when worn flaccid it makes my bulge so much more prominent.

I never take it off, for a guy who's struggled with blood circulation problems since birth (premature, genetic malformation causing poor circulation) . I mean bad, I often get Charlie horses and pins and needles in my feet... these are a game changer.

Primal rings were made for me and I can't say enough about them. 10 stars out of 5.

I started with a45mm Primal Energy and that works excellent.
I wanted to try the 40mm Spark and I’ll tell you what….. that sucker is super tight!! My cock was harder than ever!! May just be too tight. Thinking about trying the 40mm silicone rings just to get a little flex

I've worn it every day all day since it arrived.

First time trying a ring and I am not disappointed! Great quality, not too thick, looks and feels great!! I’ll definitely be looking at some other products here!!
