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 Tantus Super Soft C-Ring
men who want a reputable silicone ring under $20 and already have a sense of size. Strengths: material quality at a low price; body-safe brand reputation; simple. Limits: one size may not fit thicker girths; no graduated set; no clinical positioning.
