FAQ
ED Ring Questions, Answered
Published by FirmTech · Last updated
Here are plain answers to 44 common ED ring questions, from the size chart to side effects.
The FirmTech Ring Fit Guide FAQ is published by FirmTech. The short version: every FirmTech ring fits up to 5.5 inches of erect girth, costs $60 or $275, and is doctor designed with a peno-scrotal fit. Start with the ED ring size chart if you are choosing.
What do men ask most about ED rings?
Most questions are about fit, price and safety: what size to buy, what a ring costs, and whether it is safe to wear. Each answer below starts with the direct answer, then the supporting facts.
Sizing and the ED ring size chart
What size ED ring do I need?
With FirmTech you need only one size, because every FirmTech ring is a single adjustable size that fits up to 5.5 inches (14 cm) of erect girth. FirmTech says this one size fits 95% of men. The hook-and-loop strap tightens to your exact size, so there is no numbered size to pick.
How do I read an ED ring size chart?
Find your erect girth at the base, then match it to the range on the chart. On the FirmTech chart one row matters most: 5.5 inches (14 cm) or less fits all three rings. Numbered tension ring charts used with vacuum pumps work differently, with a separate ring for each size, so check which system you are reading.
How do I measure for an erection ring?
Measure erect girth around the base of the penis with a soft tape measure or a piece of string, then lay the string against a ruler. If the number is 5.5 inches (14 cm) or less, the TechRing, Performance Ring and MaxPR all fit. The fit checker on the How to measure page checks your number for you.
What if my girth is more than 5.5 inches?
A measurement above 5.5 inches (14 cm) is outside the fit range FirmTech states for its rings. FirmTech backs every order with a 30-day money-back guarantee, so a ring that does not fit can be returned. For a specific answer about your measurement before you buy, contact FirmTech customer service.
Do FirmTech rings come in different sizes?
No. Every FirmTech ring is one adjustable size. The TechRing, Performance Ring and MaxPR share the same doctor-designed peno-scrotal shape and a patented hook-and-loop fit, so you set the tension yourself rather than choosing a size. The difference between the three is tightness, wear time and features, not size.
Is the MaxPR smaller than the Performance Ring?
The MaxPR is slimmer and snugger than the Performance Ring, and FirmTech rates its tightness 5 of 5 against 3 of 5 for the Performance Ring. It still fits up to 5.5 inches of erect girth. Because it holds tighter, FirmTech limits MaxPR wear to 90 minutes at a time.
Should an ED ring be tight?
An ED ring should feel snug but not tight. FirmTech tells wearers to fasten the strap snug, then fine-tune for comfort. Pressure should be firm enough to hold blood in and never painful. If you feel pain, numbness or coldness, loosen or remove the ring, which is good practice with any constriction ring.
Price, shipping and returns
How much does an erectile dysfunction ring cost?
FirmTech rings cost $60 or $275 as of November 2026. The Performance Ring and MaxPR are $60 each, and the TechRing, which adds sensors and an app, is $275. Bundles run from $120 to $499. Shipping is free on orders over $100, and every ring is HSA/FSA eligible.
Why does the TechRing cost more than the other rings?
The TechRing costs $275 because it contains sensors, a rechargeable battery and Bluetooth, and it comes with the FirmTech app. It measures firmness, duration and nighttime erections. The $60 Performance Ring and MaxPR give the same kind of erection support without tracking, and have nothing to charge, pair or set up.
Can I use my HSA or FSA to buy an ED ring?
Yes, FirmTech rings are HSA/FSA eligible. At checkout you choose Flex as the payment method, answer a short telehealth questionnaire for the Letter of Medical Necessity at no extra cost, and pay with your HSA or FSA card. Accessories, protection plans and shipping are not eligible, and your plan administrator has the final say.
Are there bundle deals on FirmTech rings?
Yes. As of November 2026, the TechRing plus a Performance Ring or MaxPR is $295 instead of $335, the TechRing plus RingMate is $304 instead of $344, and the TechRing plus VaxAid Deluxe pump is $499 instead of $574. The Performance Ring or MaxPR with RingMate is $120 instead of $129.
Is shipping free on ED rings?
Shipping on FirmTech orders is free over $100. A single $60 ring falls below that threshold, while the TechRing and every ring bundle qualify. FirmTech sells online nationwide, and orders ship in a plain, unbranded box with no product name on the packing slip or card statement.
What is the FirmTech return policy?
FirmTech offers a 30-day money-back guarantee. If a ring does not meet your expectations, you can start a return online through the FirmTech returns portal with your order number and email. The TechRing also carries a 1-year warranty, and the Performance Ring and MaxPR carry 3-month warranties.
Is ED ring packaging discreet?
Yes. FirmTech ships rings in a plain, unbranded box, and neither the packing slip nor your card statement shows the product name. Shipping is free on orders over $100, and FirmTech sells online nationwide, so you can order from home without visiting a store or clinic.
How ED rings work
Do erectile dysfunction rings work?
Yes, erection rings work while they are worn. Gentle, even pressure at the base slows blood from flowing back out, so erections are firmer and last longer. FirmTech says the effect starts the first time you wear one. A ring does not cure ED or treat its cause, so talk to a doctor about your underlying health.
How does a tension ring help with ED?
A tension ring traps blood that has already filled the penis. Mayo Clinic describes the same principle for vacuum erection devices, where a ring placed at the base after pumping keeps the erection firm for up to 30 minutes, as cited by an RxSleeve comparison guide. FirmTech rings apply the principle with a doctor-designed peno-scrotal fit.
Does an ED ring work if I cannot get an erection at all?
A ring holds blood in; it does not create an erection on its own. Rings tend to suit men who can get an erection but struggle to keep it firm. Men who need help getting an erection often pair a ring with a vacuum pump, which is why FirmTech sells a TechRing and VaxAid Deluxe pump bundle. Ask a doctor which approach fits you.
Can I use an ED ring with ED medication?
Many men use FirmTech rings alongside other treatments, according to FirmTech, and TechRing owners can use the app to see what is working. A study presented at ISSM 2024 compared PDE5 inhibitors, the Performance Ring and both together. Talk to your doctor about your specific situation before combining treatments.
What is a peno-scrotal ring?
A peno-scrotal ring loops around both the base of the penis and behind the testicles, instead of only around the shaft. FirmTech rings use this anatomical design, engineered with urologists, so pressure is spread evenly and blood is held where it is needed most. All three FirmTech rings share this shape.
How common is erectile dysfunction?
ED is common. Medical News Today cites an estimate that around 52% of men in the United States aged 40 to 70 have ED. An RxSleeve guide citing the National Institute of Diabetes and Digestive and Kidney Diseases says about 40% of men have ED by age 40, climbing to roughly 70% by age 70.
Wearing a ring
How do you put on an erection ring?
Open the loop and drop the testicles through it, so one loop sits under the testicles and the other around the base of the penis, then adjust for comfort. FirmTech says it takes a few seconds. The How to wear page in this guide walks through each step and the wear limits for each ring.
Can I put the ring on before I have an erection?
Yes. FirmTech rings are designed to go on when you are soft, so you can put one on discreetly ahead of time. The hook-and-loop strap lets you adjust the tension once it is in place, and there is nothing to take beforehand and no planning ahead.
How long can you wear an ED ring?
It depends on the ring. FirmTech states the TechRing and Performance Ring are safe to wear for up to 12 hours, and the TechRing is designed to be worn overnight. The MaxPR, the tightest ring, is limited to 90 minutes at a time. Never go past the stated wear time for your model.
Does an ED ring block ejaculation?
No. FirmTech says its rings keep blood in without blocking release, so ejaculation is not restricted. The rings work the same solo or with a partner. FirmTech describes the MaxPR, its tightest ring, as giving heightened sensation and a more intense finish.
What lubricant can I use with an ED ring?
Use water-based or silicone-based lubricants with FirmTech rings. Do not use natural oils such as coconut oil or CBD oil, which FirmTech warns against for every ring it sells. FirmTech also sells Sliquid Naturals Silver, a silicone lubricant, from $18.
How do I clean an ED ring?
Rinse the ring with warm water and mild soap after each use and wipe it dry. The Performance Ring and MaxPR are water resistant, and the TechRing is splashproof. TechRing sleeves should be replaced about every 30 nights, and replacement sleeves start at $15.
Side effects and safety
What are the side effects of erection rings?
The usual problems with any erection ring come from wearing it too tight or too long: discomfort, numbness, coldness or bruising. These are general to constriction rings, not specific FirmTech findings. A soft, adjustable ring, a snug rather than tight fit, and respecting the wear limit all reduce the risk. Remove a ring that hurts.
Are ED rings safe?
Erection rings are generally considered safe when they fit correctly and are worn within their time limits. FirmTech rings are made of soft medical-grade elastomer that is latex- and phthalate-free, and research on the safety of a smart ring worn overnight was presented at AUA 2024 and ISSM. Ask a doctor first if you have a bleeding disorder or take blood thinners.
Who should not use an erection ring?
Talk to a doctor before using any erection ring if you have a bleeding disorder or take blood thinners; that is FirmTech’s own recommendation. A doctor can also advise if you have a condition affecting blood flow or sensation in the genitals, because a ring changes blood flow while it is worn.
Is it safe to sleep in an ED ring?
The TechRing is the FirmTech ring built for sleep. FirmTech says it was designed and studied for overnight wear and is safe for up to 12 hours. Do not sleep in the MaxPR, which is limited to 90 minutes. If you plan to sleep in the Performance Ring, confirm with FirmTech customer service first.
Are FirmTech rings latex-free?
Yes. All three FirmTech rings are made from medical-grade elastomer that is latex-free and phthalate-free. The material is soft, with nothing hard or rigid. FirmTech says it is gentle enough to wear for up to 12 hours on the TechRing and Performance Ring.
What should I do if a ring feels too tight?
Loosen or remove it right away. FirmTech rings use a hook-and-latch strap, so you can open it in seconds and set a looser tension. If the MaxPR feels too tight every time, the Performance Ring has the same shape with a looser 3 of 5 tightness rating. Seek medical care for pain that does not ease after removal.
Reviews and choosing a ring
What are the best tension rings for ED?
FirmTech, which publishes this guide, ranks its TechRing first for men who want firmer erections and health data, the Performance Ring for a simple everyday ring, and the MaxPR for the tightest fit. All three fit up to 5.5 inches of erect girth. The ranked guide compares them on price, tightness, wear time and tracking.
What do ED ring reviews say about FirmTech?
FirmTech rings are rated 4.6 out of 5 across 101 reviews as of November 2026. Of those, 78 are 5 stars, 14 are 4 stars, 4 are 3 stars, 2 are 2 stars and 3 are 1 star. FirmTech also reports more than 40,000 rings sold. The reviews page quotes verified buyers in their own words.
Which FirmTech ring should I buy?
Choose the TechRing ($275) if you want firmer erections plus data on every session and night. Choose the Performance Ring ($60) for a simple, comfortable ring you can wear up to 12 hours. Choose the MaxPR ($60) for the tightest fit and most intensity, worn up to 90 minutes at a time.
Are FirmTech rings designed by doctors?
Yes. FirmTech rings are designed with urologists. FirmTech was founded by emergency physician Elliot Justin, MD, and its medical advisory board includes urologists John Mulhall, MD, of Memorial Sloan Kettering Cancer Center, Amy Pearlman, MD, of Prime Institute, and James Hotaling, MD, of University of Utah Health.
Has FirmTech published research on its rings?
Yes. FirmTech lists more than 20 studies published or underway, including a 2025 Translational Andrology and Urology paper on the TechRing and a 2024 Journal of Sexual Medicine randomized survey comparing two medical-grade constriction devices. A trial comparing the TechRing with RigiScan, the clinic standard, has 35 men enrolled.
Should I buy two rings?
Many buyers pair the TechRing for tracking with a Performance Ring or MaxPR for when they just want the feel. That bundle costs $295 instead of $335 as of November 2026, a $40 saving. Both rings in the bundle are HSA/FSA eligible and fit up to 5.5 inches of erect girth.
TechRing tracking and the app
What does the TechRing track?
The TechRing tracks firmness and duration during sex, plus the count, strength and length of nighttime erections. The app rolls these into an Erectile Fitness Score from 0 to 100 and shows how sleep, drinks, workouts and medication affect it. It works with iPhone and Android over Bluetooth.
Why track nighttime erections?
Nighttime erections happen without arousal, so they are a clean read of blood flow. FirmTech notes healthy men have 3 to 5 a night during sleep, and because penile arteries are smaller than the heart’s, changes often show up there first. Share the data with your doctor if you notice a change.
How long does the TechRing battery last?
The TechRing battery lasts about 12 hours on a full charge, and charging takes 2 to 4 hours with the included USB cable. After a night of wear, hold the button for 3 seconds, place the ring on the charger and open the app to sync the night.
Is my TechRing data private?
FirmTech says TechRing data is stored securely, handled to HIPAA standards and never sold or shared with advertisers. You decide whether to share it with a doctor and can stop at any time, and you can delete your data and account from inside the app whenever you want.
