ED rings for men: which FirmTech ring fits you?
ED rings for men hold blood in an erection so it stays firmer for longer, and FirmTech makes three of them: the TechRing for $275 and the Performance Ring and MaxPR for $60 each.
This FirmTech Ring Fit Guide helps you pick the right one. All three FirmTech rings are designed with urologists, use the same anatomical peno-scrotal fit and fit up to 5.5 inches of erect girth. They differ in tightness, wear time and tracking: only the TechRing measures erection firmness, quality and duration and tracks nighttime erections in an app.

Which ED ring should I buy?
Buy the TechRing if you want firmer erections and real data on your sexual health. Buy the Performance Ring if you want simple, comfortable support you can wear for up to 12 hours. Buy the MaxPRif you want FirmTech's tightest fit and the most intense finish, worn for up to 90 minutes.
The TechRing is the right pick for most men who want to know whether a change is working. The $60 rings fit better when you only want the feel, with nothing to charge or pair.

ED rings: what they are
ED rings are soft bands worn at the base of the penis that slow blood from flowing back out, so an erection stays firmer for longer while the ring is on. You will also see them called penile tension rings, constriction rings or erection rings.
FirmTech's ED rings use a peno-scrotal design: one loop sits behind the testicles and the other around the base of the penis, which spreads pressure evenly. They are made from medical-grade, phthalate- and latex-free elastomer and close with an adjustable hook-and-loop latch. They go on soft, take seconds, and FirmTech says they do not restrict ejaculation. Read more on whether erectile dysfunction rings work.

ED rings for men: quick answers
All 40+ questions in the FAQ- Which FirmTech ring should I choose?
- Choose the TechRing if you want firmer erections plus data on every session and night. Choose the Performance Ring for simple, comfortable support you can wear up to 12 hours. Choose the MaxPR for the tightest fit and most intense finish, worn up to 90 minutes. Two-ring TechRing bundles cost $295.
- Is there an ED ring size chart for FirmTech rings?
- FirmTech rings come in one size that fits up to 5.5 inches (14 cm) of erect girth, which FirmTech says covers about 95% of men. The hook-and-loop strap adjusts to your exact size, so there is no size chart to pick from. Our size chart page explains how to check your own measurement.
- How long can I wear an erection ring?
- It depends on the ring. FirmTech rates the TechRing and Performance Ring for up to 12 hours, and the TechRing is designed for overnight wear. The MaxPR, its tightest ring, is rated for up to 90 minutes at a time. Always follow the wear time for the specific ring you own.
- Do erectile dysfunction rings work?
- ED rings work by holding blood in an erection while they are worn, which helps erections stay firmer for longer. FirmTech says the effect starts the first time you wear one, with no pills. They support an erection but do not treat the cause of ED, so talk to a doctor about what is behind it.
- What are erection ring side effects?
- With any constriction ring, too much tension or wearing it too long can cause discomfort, numbness, bruising or skin color changes. Follow the rated wear time for your ring, fasten it snug rather than tight, and remove it right away if anything hurts. These are general cautions; ask a doctor about your own risks.
- How much does an erectile dysfunction ring cost?
- FirmTech rings cost $60 for the Performance Ring or MaxPR and $275 for the TechRing. Bundles range from $120 to $499. The TechRing can also be paid in 4 interest-free payments of $68.75. Shipping is free on orders over $100, and all three rings are HSA/FSA eligible.
