If you are choosing between The Dragon and Oxballs Atomic SkinFlex, the split is not branding. The Dragon ($39.99) is the textured dual ring in this shop. Oxballs Atomic SkinFlex (check the maker’s current listing) is men between sizes, or first-timers scared of a tight ring.
Neither page on the internet can wear the device for you. Fit, and whether a stretch silicone ring is actually your problem, decide more than the brand.
