The most common questions are whether ED rings work, what they cost, which size to buy, and whether there are side effects. Jump to a topic:
An ED ring, also called a tension or constriction ring, is a band worn at the base of the penis that slows blood from flowing back out, helping an erection stay firmer for longer. FirmTech’s rings loop around both the base of the penis and behind the testicles, an anatomical peno-scrotal design FirmTech developed with urologists.
They work on the same principle: pressure at the base holds blood in the penis. The difference is mostly design intent. FirmTech’s rings are doctor designed, made of medical-grade, latex-free elastomer, use an adjustable hook-and-loop fit, and loop behind the testicles to spread pressure evenly instead of relying on a fixed-size band.
They work mechanically. Gentle pressure at the base slows blood from leaving the penis, so an erection stays firmer while the ring is worn, and the effect ends when it comes off. RxSleeve’s ED ring guide cites Mayo Clinic describing the same principle with vacuum devices, where a ring at the base keeps an erection firm for up to 30 minutes.
No. FirmTech says its rings are designed to go on when you are soft, so you can put one on discreetly ahead of time. You open the loops, place one behind the testicles and one around the base of the penis, then adjust the tension until it feels snug but comfortable. It takes a few seconds.
ED rings are for men who can get an erection but want it firmer or longer lasting. FirmTech sells its rings directly to men seeking firmer, longer-lasting erections, including men who want to track their sexual health with the TechRing. Men with a medical condition should ask their doctor before using any constriction device.
FirmTech says many men use the TechRing alongside other treatments and use the app to see what is working. RxSleeve, citing a review in the Cleveland Clinic Journal of Medicine, notes that up to 40% of men do not get a satisfactory response from PDE5 inhibitors alone. Ask your doctor about your specific situation before combining treatments.
FirmTech says its rings keep blood in without blocking release, so they do not restrict ejaculation. That is a design goal of the peno-scrotal shape, which spreads pressure across the base of the penis and behind the testicles. If you notice anything unusual while wearing a ring, remove it and talk to a doctor.
Among FirmTech’s three rings, the TechRing is this guide’s top pick for most men: it gives the same firmness support as the others, allows up to 12 hours of wear, and is the only one that measures firmness, duration and nighttime erections. The Performance Ring is the simplest choice at $60, and the MaxPR is the tightest.
Both support firmer, longer-lasting erections, share the same peno-scrotal design, and can be worn for up to 12 hours. The TechRing ($275) adds sensors, a Bluetooth app, nighttime erection tracking and a 1-year warranty. The Performance Ring ($60) has nothing to charge or pair and carries a 3-month warranty.
Both cost $60 and use the same doctor-designed shape. The MaxPR is slimmer and snugger, rated 5 of 5 for tightness on FirmTech’s product page, versus 3 of 5 for the Performance Ring. The trade-off is wear time: up to 90 minutes for the MaxPR versus up to 12 hours for the Performance Ring.
The MaxPR. FirmTech rates it 5 of 5 for tightness and 5 of 5 for pleasure, describing it as slimmer and snugger than the original for fuller erections and a more intense finish. Because of the extra pressure, FirmTech lists its safe wear time as up to 90 minutes at a time.
No. Neither has sensors, a battery or an app connection. FirmTech positions them as erection support without tracking. Only the TechRing has built-in sensors that measure firmness, duration and nighttime erections, and it is the only FirmTech ring that needs charging, so the $60 rings are ready to use straight from the box.
Some men do. FirmTech sells a TechRing plus Performance Ring bundle and a TechRing plus MaxPR bundle, each listed at $295 instead of $335. The idea is to track with the TechRing and keep a simple ring for times when you just want the feel, without charging or pairing anything.
No. This guide is published by FirmTech and compares only FirmTech’s three rings: the TechRing, the Performance Ring and the MaxPR. To compare other brands, broader roundups such as Healthline’s ring guide cover many styles, and a urologist can advise on which constriction devices suit your situation.
FirmTech’s rings cost $60 for the Performance Ring or MaxPR and $275 for the TechRing, as listed in November 2026. Across the wider market, Healthline notes that rings can top $100 depending on the brand, materials and features. Sensors and an app are the main reason the TechRing costs more.
The TechRing includes built-in sensors, a USB-rechargeable battery that lasts about 12 hours, a Bluetooth connection to the FirmTech app, and nighttime erection tracking. It also carries a 1-year warranty on electronics plus 2 sleeve replacements, compared with a 3-month warranty on the $60 Performance Ring and MaxPR.
Yes, for FirmTech’s rings. The TechRing, Performance Ring and MaxPR, including bundles that pair them, are HSA/FSA eligible through Flex at checkout. A short telehealth questionnaire provides the Letter of Medical Necessity. Accessories and shipping are not eligible, and your plan administrator has the final say on coverage.
FirmTech’s TechRing page lists an option of 4 interest-free payments of $68.75. Availability depends on the checkout provider and your eligibility, so check the payment options shown on the TechRing page at getfirmtech.com when you order. The $60 rings are usually paid in full at checkout.
The Performance Ring and MaxPR have no ongoing costs beyond cleaning. For the TechRing, FirmTech recommends replacing the sleeve about every 30 nights, with replacement sleeves listed from $15. An optional TechRing protection plan is offered at $29 for 1 year or $39 for 2 years.
FirmTech offers free discreet shipping on orders over $100. The TechRing qualifies on its own at $275. A single Performance Ring or MaxPR at $60 falls under that threshold, while bundles such as a Performance Ring plus RingMate ($120) or a TechRing bundle ($295) qualify.
FirmTech does not sell multiple sizes. All three rings are one size that FirmTech says fits 95% of men, up to 5.5 inches (14 cm) of erect girth, with an adjustable hook-and-loop strap. If your erect girth at the base measures 5.5 inches or less, the ring is designed to fit.
When erect, wrap a soft measuring tape or a piece of string around the base of the penis, then measure the string against a ruler. If it reads 5.5 inches (14 cm) or less, FirmTech’s rings are designed to fit. FirmTech’s 30-day money-back guarantee applies if it does not work for you.
FirmTech lists its rings as fitting up to 5.5 inches of erect girth, so a larger girth falls outside the stated range. In that case, contact FirmTech before buying to ask about fit, or talk to a doctor about other devices. FirmTech’s contact page at getfirmtech.com/contact routes product questions to customer service.
Snug but not tight. FirmTech’s adjustable hook-and-loop strap lets you set the tension so pressure is firm but never painful. If you feel pain, numbness or coldness, loosen or remove the ring. The MaxPR is designed to be tighter by default, which is why its safe wear time is shorter.
FirmTech makes them from soft, medical-grade, latex-free and phthalate-free elastomer, with nothing hard or rigid. The Performance Ring is rated 3 of 5 for tightness and described as a comfortable everyday fit, and both the TechRing and Performance Ring are rated for up to 12 hours of wear.
Rings can help men who get an erection but lose firmness, because pressure at the base slows blood leaving the penis. The effect is mechanical and lasts only while worn. RxSleeve cites Mayo Clinic describing a ring keeping an erection firm for up to 30 minutes after a vacuum pump. Rings do not treat underlying causes.
Rings are often discussed for venous leak because they slow blood from draining out. RxSleeve, citing the Cleveland Clinic Journal of Medicine, notes up to 40% of men do not get a satisfactory response from PDE5 inhibitors and that a leaking valve is a frequent cause. A urologist can confirm whether venous leak applies to you.
Commonly reported effects of constriction rings include temporary numbness, coldness, bruising or discomfort, usually from wearing a ring too tight or too long. Follow the wear time for your ring: up to 12 hours for the TechRing and Performance Ring, up to 90 minutes for the MaxPR. Remove it if you feel pain and talk to a doctor.
Talk to a doctor first if you have a bleeding disorder, take blood thinners, have a circulation condition, or have reduced sensation in the genital area. A doctor can tell you whether a constriction device is safe for you. FirmTech’s rings were designed with urologists, but they do not replace personal medical advice.
Only in a ring rated for it. FirmTech says the TechRing is designed and studied for overnight wear for up to 12 hours, which is how it tracks nighttime erections. The Performance Ring is also rated for up to 12 hours. The MaxPR is limited to 90 minutes at a time, so do not sleep in it.
Use water-based or silicone-based lubricants with any FirmTech ring. FirmTech advises against natural oils such as coconut oil or CBD oil. After each use, rinse the ring with warm water and mild soap and let it dry. The Performance Ring and MaxPR are water resistant, and the TechRing is splashproof.
FirmTech says healthy men have 3 to 5 erections a night during sleep, and because they happen without arousal they are a clean read of blood flow. Penile arteries are smaller than the heart’s, so circulation changes can show up there first. The TechRing measures these erections at home, without a sleep lab.
Very common. RxSleeve’s ED ring guide, citing the National Institute of Diabetes and Digestive and Kidney Diseases, reports that about 40% of men have ED by age 40, rising to roughly 70% by age 70. ED can be an early sign of other health issues, so it is worth discussing with a doctor.

FirmTech says its rings are designed with urologists. Its founder and CEO, Elliot Justin, MD, is an emergency physician, and its medical advisory board includes urologists John Mulhall, MD, Amy Pearlman, MD, and James Hotaling, MD. All three rings share the same doctor-designed peno-scrotal shape.
During sex it measures firmness and duration. Overnight it counts nighttime erections and measures their strength and length. The FirmTech app rolls this into an Erectile Fitness Score from 0 to 100, and lets you log sleep, drinks, workouts and medication to see what affects your numbers.
Yes. The FirmTech app is free with the TechRing, works on iPhone and Android, and connects over Bluetooth. FirmTech says setup takes about three minutes: charge the ring with the included USB cable, pair it in the app, then wear it during sex or overnight and your data syncs.
About 12 hours on a full charge, according to FirmTech, which covers a full night of tracking. A full charge takes 2 to 4 hours with the included USB cable. The Performance Ring and MaxPR have no battery at all, so there is nothing to charge.
FirmTech says TechRing data is stored securely and handled to HIPAA standards, is never sold or shared with advertisers, is shared with your doctor only if you choose, and can be deleted from inside the app at any time. FirmTech’s privacy policy has the full details.
FirmTech lists published research including a 2025 Translational Andrology and Urology paper on the TechRing and a 2024 Journal of Sexual Medicine survey study comparing two medical-grade penile constriction devices.
