How they actually work
The Dragon: a textured dual ring. This site does not make disease-treatment claims for it FirmTech Performance Ring: same venous restriction, with on-the-fly tightness and a shape FirmTech says is built for longer wear during sex
Sizing
The Dragon sizing: 1.25 in shaft ring, 1.75 in back ring, 2x stretch, girth 4.0 to 6.75 in (store listing). FirmTech Performance Ring: adjustable tightness, one band rather than numbered sizes.
Regulatory sticker
FirmTech Performance Ring is sold as a medical device. The other is not. Buy the listing if you need a receipt. Buy the simpler ring if you need to know whether a stretch silicone ring is even your problem.
Who should buy The Dragon
the textured dual ring in this shop. Strengths the maker can honestly claim: store-published two-ID chart; texture. Limits: dual ring, not a single band; figures are store copy.
Who should buy FirmTech Performance Ring
men who hated guessing silicone size and want to micro-adjust tension. Strengths: adjustable; no dedicated size chart; urologist-adjacent marketing; easier on/off than a closed loop. Limits: hook-and-loop bulk; not a $25 experiment; published head-to-head data is still limited; maker discusses long wear; this site still uses a thirty-minute cap.
When to buy the Mammoth Force one
The Dragon is ours. FirmTech Performance Ring is not. Ours wins on price and on not needing an account. Theirs wins where the table says it wins: adjustable; no dedicated size chart.
