If you are choosing between Eddie by Giddy and FirmTech TechRing, the split is not branding. Eddie by Giddy ($188-$288) is men who want a medical-device purchase, HSA billing, or who found circular rings painful on the urethra. FirmTech TechRing ($275) is men who want a log for a urologist, not just a tighter erection.
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.

Both are sold with medical-device positioning. Listing is not the same as FDA approval of effectiveness. See each maker’s own language.
Who should buy Eddie by Giddy
men who want a medical-device purchase, HSA billing, or who found circular rings painful on the urethra. Strengths the maker can honestly claim: Class II listing; HSA/FSA eligibility stated by Giddy; sized system; company-cited 12-week trial. Limits: several times the price of a silicone set; still cannot create an erection from nothing.
Who should buy FirmTech TechRing
men who want a log for a urologist, not just a tighter erection. Strengths: data if you want it; adjustable; aimed at men working with a clinician. Limits: you pay for sensors you may never look at; charging and app overhead; still a ring.
