How they actually work
FirmTech Performance Ring: same venous restriction, with on-the-fly tightness and a shape FirmTech says is built for longer wear during sex Oxballs Oxsling: constriction plus scrotal positioning. More toy than ED device.
Sizing
FirmTech Performance Ring sizing: adjustable tightness, one band rather than numbered sizes. Oxballs Oxsling: stretch, one size with a lot of give.
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 FirmTech Performance Ring
men who hated guessing silicone size and want to micro-adjust tension. Strengths the maker can honestly claim: 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.
Who should buy Oxballs Oxsling
men who want bulge, ball stretch and erection support together. Strengths: cock-and-ball in one; soft blend; stays put better than a thin band for some men. Limits: looks like a toy, which some partners will not want; not an ED clinical product.
