If you are choosing between Mammoth Ring and Amazon 7-size silicone ring set, the split is not branding. Mammoth Ring ($39.99) is a single stretch ring in the store’s 4.5 to 7.75 in girth band. Amazon 7-size silicone ring set (check the maker’s current listing) is almost nobody as a daily device. Useful only as a sizing experiment you then throw away..
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.
