FAQ
These are 48 answers about erection rings, sizing, side effects and the FirmTech TechRing, Performance Ring and MaxPR. Each answer starts with the short version, then adds the facts behind it.
Published by FirmTechLast updated November 2026
Buy the FirmTech TechRing ($275) if you want performance support plus tracking, the Performance Ring ($60) for simple all-day comfort, or the MaxPR ($60) for the tightest fit. All three fit erect girths up to 5.5 inches. Compare them side by side.
An erection ring is a band worn around the base of the penis, and sometimes behind the testicles, that slows blood from flowing back out so erections feel firmer and last longer. FirmTech rings use an anatomical peno-scrotal design that loops around both the base and the testicles, and they work without pills or a prescription.
Erection rings work mechanically. Gentle, even pressure at the base slows blood from leaving the penis, so an erection stays firmer for longer. FirmTech describes the effect as lasting only while the ring is worn. Nothing is swallowed or absorbed, which is why the rings need no prescription.
A C ring is an informal name for a cock ring or erection ring, a constriction band worn at the base of the penis. The FirmTech versions are the Performance Ring and MaxPR at $60 each and the TechRing at $275. All three are doctor designed with an adjustable hook-and-loop fit rather than a fixed, solid loop.
Both describe a band that holds blood in the penis. "Tension ring" is often used for rings slipped on after a vacuum pump. Mayo Clinic, as cited by RxSleeve, describes a ring placed after pumping keeping an erection firm for up to 30 minutes. FirmTech also sells the TechRing in a bundle with the VaxAid Deluxe water-based pump.
A wearable ED device is something worn on the body to support or measure erections. FirmTech calls the TechRing the world’s first smart wearable for the penis: it works as an erection ring and uses built-in sensors to measure firmness, duration and nighttime erections, with results in an app for iPhone and Android.
FirmTech rings are doctor designed with leading urologists. The company was founded by Elliot Justin, MD, FACEP, an emergency physician. Its medical advisory board includes urologists John Mulhall, MD, Amy Pearlman, MD and James Hotaling, MD, MS, plus Stanley Lewis, MD, MPH, who brings an internal medicine view.
With FirmTech rings, you do not need to pick a size. FirmTech says one size fits 95% of men, up to 5.5 inches (14 cm) of erect girth, and the hook-and-loop strap adjusts to your exact size. If your erect girth is above 5.5 inches, contact FirmTech before ordering to ask about fit.
When erect, wrap a soft tape measure or a piece of string around the base of the penis. That number is your girth. FirmTech says that if it is 5.5 inches (14 cm) or less, its rings fit. To convert girth to the diameter used by solid rings, divide the girth by 3.1416.
Divide your circumference by pi, about 3.1416. A 5 inch girth equals about 1.59 inches, or roughly 40 mm, of diameter. Diameter matters most for solid, fixed-size rings. FirmTech adjustable rings are sized by girth instead, with a stated fit of up to 5.5 inches erect.
Yes. The size chart on this guide’s home page converts erect girth from 4 to 7 inches into centimeters and diameter, and marks which measurements fall inside the FirmTech stated fit of up to 5.5 inches. All three FirmTech rings share that range, so one chart covers the TechRing, Performance Ring and MaxPR.
FirmTech states its rings fit up to 5.5 inches (14 cm) of erect girth, so a larger measurement falls outside the published range. Contact FirmTech through getfirmtech.com/contact before buying to ask about fit. FirmTech also offers a 30-day money-back guarantee if a ring does not meet your expectations.
Yes. FirmTech says its rings are designed to go on while you are soft, so you can put one on discreetly ahead of time. You hold the loop open, place the testicles through one loop, set the other loop around the base of the penis, then adjust the tension for comfort.
FirmTech rings are made from soft, medical-grade elastomer, with a patented hook-and-loop fit and nothing hard or rigid. FirmTech rates the TechRing and Performance Ring at 3 of 5 for tightness, aimed at a secure, comfortable fit, and the MaxPR at 5 of 5, its tightest option.
Yes. All three FirmTech rings, the TechRing, Performance Ring and MaxPR, are made from medical-grade elastomer that FirmTech lists as phthalate free and latex free. That makes them an option for men who avoid latex. Anyone with a known sensitivity to other materials should check with a doctor first.
Pick the TechRing ($275) if you want performance support plus data on firmness, duration and nighttime erections. Pick the Performance Ring ($60) for a comfortable, simple ring you can wear up to 12 hours. Pick the MaxPR ($60) if you want the tightest FirmTech fit, worn up to 90 minutes at a time.
Both support firmer, longer-lasting erections with the same peno-scrotal design and up to 12 hours of wear. The TechRing adds built-in sensors, a Bluetooth app and a USB rechargeable 12-hour battery, and carries a 1-year warranty. The Performance Ring has nothing to charge and a 3-month warranty, at $60 instead of $275.
It depends on what you want. The MaxPR is slimmer and snugger, rated 5 of 5 for tightness and pleasure, but FirmTech limits it to 90 minutes of wear. The Performance Ring is rated 3 of 5 for tightness, aims for everyday comfort and can be worn up to 12 hours. Both cost $60.
Only if you want data. Every FirmTech ring supports firmer, longer-lasting erections; tracking is what sets the TechRing apart. It suits men who want to see firmness, duration and nighttime erections over time, or share data with a doctor. If you just want the feel, the Performance Ring or MaxPR covers that for $60.
Yes. The FirmTech shop lists the TechRing plus Performance Ring and the TechRing plus MaxPR at $295 each, compared with $335 bought separately, a $40 saving. FirmTech suggests the pairing for men who want to track with the TechRing and keep a simple ring for when they just want the feel.
The Performance Ring is the simplest starting point: $60, an adjustable comfort fit, up to 12 hours of wear and nothing to charge or pair. Men who already know they want health data can start with the TechRing, which shares the same 3 of 5 tightness rating and 12-hour wear time.
Yes. FirmTech says its rings work the same way solo or with a partner, and the TechRing tracks every session either way. FirmTech also sells RingMate, a three-speed vibrator for her that slides onto any FirmTech ring, for $69 on its own or $120 bundled with the Performance Ring or MaxPR.
No. FirmTech says its rings keep blood in without blocking release, so they do not restrict ejaculation. FirmTech describes the extra pressure of the MaxPR as giving heightened sensation and a more intense finish, while the Performance Ring and TechRing aim for a comfortable, secure fit.
The TechRing measures erection firmness, quality and duration during sex, plus the count, strength and length of nighttime erections. 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 results.
Nighttime erections happen without arousal, so FirmTech treats them as a clean read of blood flow. FirmTech notes that healthy men have 3 to 5 erections a night during sleep and that changes often show up there first. The TechRing is designed and studied for overnight wear of up to 12 hours.
The FirmTech app works on iPhone and Android and connects to the TechRing over Bluetooth. The app is free with the TechRing. The Performance Ring and MaxPR have no sensors or app connection, so they do not need a phone at all.
FirmTech lists up to 12 hours on a full charge. A full charge takes 2 to 4 hours with the included USB charger. After overnight wear, you hold the button for 3 seconds, put the ring on the charger and open the app to sync the night.
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 anytime. You can also delete your data and account from inside the app whenever you want.
Yes, if you choose to. The FirmTech app lets you decide who sees your data. FirmTech also runs a provider program in which partner clinics can, with patient permission, view firmness, duration and nighttime erections between visits.
Yes. 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 constriction devices. Research underway includes a trial comparing the TechRing with RigiScan, the clinic standard, with 35 men enrolled.
Most problems come from a ring that is too tight or worn too long: discomfort, numbness, bruising, or a cold or discolored penis. Remove the ring right away if any of these happen. FirmTech rings use an adjustable hook-and-loop strap so you can set the tension, and each ring has a stated maximum wear time.
It depends on the ring. FirmTech rates the TechRing and Performance Ring for up to 12 hours and the MaxPR for up to 90 minutes. General guidance for other rings is much shorter: Tenga recommends no more than 20 to 30 minutes at a time. Always follow the limit for the specific ring you own.
Only if the ring is designed for it. FirmTech says the TechRing is designed and studied for overnight wear of up to 12 hours, and lists a study on the safety of a smart constriction ring worn overnight, presented at AUA 2024. Do not sleep in a tight ring like the MaxPR, which is limited to 90 minutes.
Talk to a doctor before using any erection ring if you have a bleeding disorder, take blood thinners, or have a circulation or nerve condition. Because erection problems can be linked to heart and blood vessel health, a doctor visit is also wise if ED is new for you.
FirmTech says many men use the TechRing alongside other treatments and use the app to see what is working. FirmTech also presented research at ISSM 2024 comparing PDE5 inhibitors, the Performance Ring and both together. Talk to your doctor about your specific situation before combining treatments.
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. The TechRing is splashproof, and the Performance Ring and MaxPR are water resistant.
Rinse FirmTech rings with warm water and mild soap after each use and wipe dry. For vibrating rings from other makers, Emen8 advises not submerging them and instead using a sex toy disinfectant, left for 10 minutes, then wiping with a towel. FirmTech suggests replacing TechRing sleeves, from $15, about every 30 nights.
As listed on getfirmtech.com in November 2026, the TechRing costs $275 and the Performance Ring and MaxPR cost $60 each. Two-ring bundles pairing the TechRing with either simpler ring cost $295. Free discreet shipping applies to orders over $100.
Yes. The TechRing, Performance Ring and MaxPR, including bundles that pair them, are HSA/FSA eligible. At checkout you choose Flex, answer a short telehealth questionnaire for the Letter of Medical Necessity at no extra cost, then pay. Your plan administrator has the final say on coverage.
No. FirmTech rings work without pills or a prescription and are sold online at getfirmtech.com. HSA/FSA purchases need a Letter of Medical Necessity, which Flex provides through a short questionnaire at checkout at no extra cost.
Yes. FirmTech ships in a plain, unbranded box with no product name on the packing slip or card statement. Shipping is free on orders over $100, which covers the TechRing on its own or any two $60 rings together.
FirmTech offers a 30-day money-back guarantee. The TechRing carries a 1-year warranty from purchase, and the Performance Ring, MaxPR and RingMate each carry a 3-month warranty. Returns start online through the FirmTech returns portal; warranty claims go to customer service by email with your order number.

Basic rings cost much less: Emen8 notes rubber cock rings start from $3 and silicone ones from $7. FirmTech $60 rings add a doctor-designed peno-scrotal shape, adjustable tension, medical-grade latex-free material and a warranty, and the $275 TechRing adds tracking. Whether that is worth it depends on how much fit and data matter to you.
They work differently. Pills act on blood flow chemically; rings hold blood in mechanically while worn. A review in the Cleveland Clinic Journal of Medicine, cited by RxSleeve, found up to 40% of men do not get a satisfactory response from PDE5 inhibitors like Viagra or Cialis. Some men use both, so ask your doctor.
In a randomized survey study summarized by ISSM, 79.6% of participants recommended FirmTech compared with 53.1% for Eddie by Giddy. Participants kept the devices and received a $50 gift card for participation. FirmTech lists the study as published in the Journal of Sexual Medicine in 2024.
Very common. According to the National Institute of Diabetes and Digestive and Kidney Diseases, as cited by RxSleeve, about 40% of men have ED by age 40, climbing to roughly 70% by age 70. Erection rings are one drug-free option men use, and a doctor can help find the cause.
None of the three FirmTech rings vibrate. If you want vibration, FirmTech sells RingMate, a three-speed vibrator for her that slides onto any FirmTech ring, for $69. Vibrating rings from other makers need careful cleaning; Emen8 advises against submerging them.
