Men most often ask which ring to choose, what size they need, and how long they can wear it. Short answers: start with the Performance Ring unless you want the tightest fit; both non-tech rings fit up to 5.5 inches of erect girth; wear time is up to 12 hours for the Performance Ring and 90 minutes for the MaxPR.

What an ED ring is
What is an ED ring for men?
An ED 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. The FirmTech Performance Ring and MaxPR are this kind of ring, made from medical-grade elastomer with a loop that also sits behind the testicles. Neither needs pills, a prescription, charging or an app.
How does an erection ring work?
It works mechanically. Gentle pressure at the base slows blood leaving the penis, so an erection stays firmer while the ring is on. The effect lasts only as long as you wear it. FirmTech describes this as keeping blood where it counts, with pressure spread evenly by its peno-scrotal loop design.
Is an ED ring a cure for erectile dysfunction?
No. A ring helps maintain an erection while it is worn; it does not treat the cause of erectile dysfunction. ED can be linked to blood vessel, hormone or nerve health, so a doctor visit is worthwhile if your erections change. Many men use a ring alongside other care their doctor recommends.
What is the difference between c-rings and ED rings?
"C-ring" is a casual name for any cock ring, from fixed steel bands to stretchy silicone loops. "ED ring" or "constriction ring" usually means a ring meant to help hold an erection. The FirmTech rings are adjustable, doctor-designed constriction rings with a hook-and-latch closure rather than a fixed, closed circle.
What does peno-scrotal fit mean?
It means the ring wraps around both the base of the penis and behind the testicles, rather than the penis alone. FirmTech uses this anatomical design on all three of its rings so pressure is spread evenly. One loop sits under the testicles and the other around the base of the penis.
Do I need a prescription for an ED ring?
No. The FirmTech Performance Ring and MaxPR are sold online without a prescription and work without pills. If you want to pay with HSA or FSA funds, the checkout partner Flex handles the Letter of Medical Necessity the IRS asks for through a short telehealth questionnaire, at no extra cost.
Choosing between the Performance Ring and MaxPR
Which is better, the Performance Ring or the MaxPR?
For most men the Performance Ring is the easier first choice: FirmTech rates it 3 of 5 for tightness and lists it for up to 12 hours of wear. The MaxPR suits men who want the tightest fit FirmTech makes, rated 5 of 5, and more intense sensation, but it is limited to 90 minutes per wear.
What is the difference between the Performance Ring and the MaxPR?
Both cost $60, use the same doctor-designed peno-scrotal shape and hook-and-latch closure, and are made of medical-grade elastomer. The MaxPR is slimmer and snugger. FirmTech rates the Performance Ring 3 of 5 for tightness and pleasure with wear up to 12 hours, and the MaxPR 5 of 5 for both with wear up to 90 minutes.
Should I buy both rings?
Some men do. Each costs $60, so two rings come to $120, which passes the $100 free shipping threshold. The Performance Ring covers longer, more comfortable wear and the MaxPR covers shorter sessions where you want maximum firmness. If unsure, start with the Performance Ring and lean on the 30-day money-back guarantee.
Do the Performance Ring and MaxPR have electronics?
No. Neither has sensors, a battery, Bluetooth or an app, so there is nothing to charge, pair or set up. The FirmTech TechRing, at $275, is the only FirmTech ring with sensors and app tracking of erection firmness, quality, duration and nighttime erections.
When should I choose the TechRing instead?
Choose the TechRing if you want data as well as performance support. It measures erection firmness, quality and duration and tracks nighttime erections through an app, and it costs $275. If you only want firmer, longer-lasting erections with nothing to charge, the Performance Ring or MaxPR at $60 covers that.
Which FirmTech ring is most comfortable?
FirmTech describes the Performance Ring as its comfortable everyday fit, rated 3 of 5 for tightness, and lists it as safe to wear for up to 12 hours. The MaxPR is intentionally tighter. Both use soft medical-grade elastomer with adjustable tension, so you can loosen the fit within each ring’s range.
Fit and sizing
What size ED ring do I need?
FirmTech rings are one size with adjustable tension and fit up to 5.5 inches (14 cm) of erect girth measured at the base, so there is no size to pick. Measure with a soft tape or string around the base when erect. At 5.5 inches or less, the Performance Ring and MaxPR fall within the listed fit.
How do I measure for an erection ring?
When erect, wrap a soft tape measure or a piece of string around the base of the penis. Mark where it meets, then measure the string with a ruler. Compare the number to the listed fit of up to 5.5 inches, which is 14 cm. The fit checker on our size chart page does the comparison for you.
Is there an ED ring size chart for FirmTech rings?
Yes, and it is short because the rings are one size. All three FirmTech rings list a fit up to 5.5 inches (14 cm) of erect girth with adjustable tension. Our size chart page shows that range in inches and centimeters and explains how tightness differs between the Performance Ring and the MaxPR.
What if my girth is over 5.5 inches?
Then you are outside the fit FirmTech lists for its rings, so ask FirmTech before buying. Contact the company through its contact page with your measurement. A ring that is too tight can be uncomfortable or unsafe, so do not force a fit beyond the listed range.
Can I adjust how tight the ring is?
Yes. Both the Performance Ring and the MaxPR use a hook-and-latch design with adjustable tension, so you control how snug it feels. The MaxPR is built slimmer and tighter overall, so expect it to feel snugger than the Performance Ring. Aim for snug, never painful.
Is the MaxPR too tight for beginners?
It can be. FirmTech calls the MaxPR its tightest ring, rated 5 of 5 for tightness, and limits wear to 90 minutes. Men new to rings often start with the Performance Ring, rated 3 of 5, then try the MaxPR once they know how a ring feels. Remove any ring that hurts.
Wear time, safety and side effects
How long can I wear an ED ring?
It depends on the ring. FirmTech lists the Performance Ring as safe to wear up to 12 hours and the MaxPR up to 90 minutes. Many conventional rings carry shorter limits: Healthline reports most manufacturers recommend removing a ring after 20 minutes, and the SMSNA says users are typically advised to stay under 30 minutes.
Why can the Performance Ring be worn longer than most rings?
FirmTech lists the Performance Ring as safe for up to 12 hours because of its soft, adjustable elastomer design. menMD, writing about the FirmTech device, says its material allows blood to move in and out of the penis, making it safe beyond 30 minutes. The SMSNA notes that compliant materials and easy-removal hooks are designed with safety in mind.
What are erection ring side effects?
Possible issues with any constriction ring include discomfort, numbness, bruising, a cold or discolored penis, and trouble removing a ring that is too tight. The SMSNA warns that extended wear risks complications including penile entrapment. Remove the ring right away if you feel pain or numbness, and stay within each ring’s listed wear time.
Is it safe to sleep in the Performance Ring?
FirmTech’s overnight guidance is written for the TechRing, which is designed and studied for overnight wear. For the Performance Ring, FirmTech lists wear time up to 12 hours. If you plan to wear any ring overnight, check with FirmTech or your doctor first. Do not sleep in the MaxPR, which is limited to 90 minutes.
Who should not use an erection ring?
Talk to a doctor first if you have a bleeding disorder, take blood thinners, have reduced sensation in the genitals, or have any condition that affects blood flow. These are general cautions for constriction rings. A doctor can also check whether ED reflects a heart, hormone or nerve issue that needs its own care.
Does an ED ring restrict ejaculation?
FirmTech states that its ring design keeps blood in without blocking release, and the Performance Ring and MaxPR share the same peno-scrotal shape. A tighter ring can change how orgasm feels: FirmTech describes the MaxPR as giving heightened sensation and a more intense finish.
Can I use an ED ring with ED medication?
Many men pair a ring with other treatment, and FirmTech research presented at ISSM 2024 compared PDE5 inhibitors, the Performance Ring and both together. Ask your doctor before combining a device with medication. Up to 40% of men do not get a satisfactory response from PDE5 inhibitors, per a Cleveland Clinic Journal of Medicine review cited by RxSleeve.
What should I do if the ring feels too tight?
Loosen the hook-and-latch closure or take the ring off. A ring should feel snug but never painful, cold or numb. If the MaxPR feels too tight even when loosened, the Performance Ring is the less tight FirmTech option. Remove any ring immediately if the skin changes color.
Materials and care
What are FirmTech rings made of?
The Performance Ring and MaxPR are made of medical-grade elastomer that is phthalate-free and latex-free, and both are water resistant. There is nothing hard or rigid against the body, unlike metal c-rings, and the hook-and-latch closure lets you open the ring instead of sliding a fixed circle on and off.
Are FirmTech rings latex-free?
Yes. Both the Performance Ring and the MaxPR are latex-free and phthalate-free medical-grade elastomer, which matters for men with a latex sensitivity. The TechRing is also made from medical-grade, phthalate- and latex-free elastomer, according to the FirmTech comparison chart.
How do I clean the Performance Ring or MaxPR?
Rinse it with warm water and mild soap after each use, then let it dry, which is the care FirmTech recommends. Both rings are water resistant. Store the ring somewhere clean and dry, and look it over before each use so you notice any tears or overstretched areas.
What lube can I use with an ED ring?
Use water-based or silicone-based lubricants only. FirmTech says not to use natural oils such as coconut oil or CBD oil with any of its rings. A little lube can also make it easier to position the loops at the base.
Can the ring get wet?
Yes. The Performance Ring and MaxPR are water resistant and are cleaned with warm water and mild soap, so contact with water is fine. Rinse and dry the ring after use. The TechRing, which has electronics, is rated splashproof instead.
Price, shipping and buying
How much does an ED ring cost?
The FirmTech Performance Ring and MaxPR cost $60 each, and the TechRing costs $275. Pairing either non-tech ring with RingMate, a vibrator for her that slides onto the ring, costs $120 instead of $129. All rings are sold online at getfirmtech.com.
Are FirmTech rings HSA or FSA eligible?
Yes. The TechRing, Performance Ring and MaxPR, plus bundles that pair them, are HSA/FSA eligible. At checkout choose Flex, answer a short telehealth survey that provides the Letter of Medical Necessity at no extra cost, and pay with your card. Your plan administrator has the final say on coverage.
Is shipping discreet?
Yes. FirmTech ships the Performance Ring and MaxPR in a plain, unbranded box, with no product name on the packing slip or card statement. Shipping is free on orders over $100, so a single $60 ring does not reach the threshold, while two rings or a ring with RingMate does.
What is the warranty and return policy?
The Performance Ring and MaxPR each carry a 3-month warranty from the date of purchase. FirmTech also offers a 30-day money-back guarantee if a product does not meet your expectations. Start a return through the FirmTech returns portal, or email customer service with your order number and a short description.
Where can I buy the Performance Ring and MaxPR?
They are sold online at getfirmtech.com. FirmTech also lists doctors, men’s health clinics and stores that carry its rings on its where-to-buy map. Buying direct comes with free discreet shipping on orders over $100.
Why have ring prices gone up in general?
Market-wide, most rings are made in China, which produces about 70 percent of the world’s intimacy products. US duties on Chinese goods rose from 84 percent to 145 percent in April 2025, and the higher landed cost fed through to shelf prices, according to the Dataintelo cock ring market report. FirmTech lists the Performance Ring and MaxPR at $60.
Using a ring and the evidence behind it
How do I put on a FirmTech ring?
Unhook the latch and open the loops. Hold one loop open and pass the testicles through it, then bring the other loop around the base of the penis. Close the hook-and-latch and adjust the tension until it feels snug. FirmTech says it goes on in seconds.
Can I use it solo or with a partner?
Both. The ring works the same way either way. Couples can add RingMate, a three-speed vibrator for her that slides onto any FirmTech ring. It costs $69 on its own, or $120 bundled with either the Performance Ring or the MaxPR.
How quickly does an ED ring work?
It works while you wear it. FirmTech says the Performance Ring needs no pills, prescription or planning ahead. Because the effect is mechanical, it starts once the ring is on and stops when you take it off.
Do doctors recommend constriction rings?
Medical groups describe them as an option. The SMSNA explains the different types of penile constriction rings, and RxSleeve cites Mayo Clinic describing a ring used with a vacuum device to keep an erection firm for up to 30 minutes. FirmTech rings were designed with leading urologists, including members of its medical advisory board.
What did the study comparing FirmTech and Eddie by Giddy find?
In a randomized survey study summarized by the ISSM, 79.6% of participants recommended FirmTech compared to 53.1% for Eddie by Giddy. Participants kept the devices and received a $50 gift card for taking part. The study was published in the Journal of Sexual Medicine in 2024.
How common is erectile dysfunction?
It is common and becomes more so with age. RxSleeve, citing the National Institute of Diabetes and Digestive and Kidney Diseases, reports that about 40% of men have ED by age 40, climbing to roughly 70% by age 70. A doctor visit is worthwhile because ED can be an early sign of other health issues.
Is an ED ring the same as a tension ring?
Mostly. "Tension ring" usually means a ring used with a vacuum erection pump, slipped onto the base after pumping to hold the erection, which RxSleeve cites Mayo Clinic describing for up to 30 minutes. The Performance Ring and MaxPR are adjustable constriction rings you wear without a pump.
