What is the most common question about ED rings?
The most common question is whether ED rings work, and for many men they do, by slowing blood from leaving the penis while worn. The answers below cover that and 42 more questions.
What ED rings are
What is an ED ring?
An ED ring is a soft band worn at the base of the penis that helps keep an erection firmer for longer. FirmTech makes three: the MaxPR and Performance Ring at $60 each, and the TechRing at $275, which also measures erections. All three are doctor designed with an anatomical peno-scrotal fit.
How does an ED ring work?
An ED ring works by putting gentle pressure at the base of the penis so blood that has flowed in stays in place longer. FirmTech describes the effect as entirely mechanical: it lasts only as long as the ring stays on. The MaxPR adds firmer pressure than the Performance Ring for a fuller erection.
Do erectile dysfunction rings work?
Yes, for many men ED rings help erections stay firmer for longer while the ring is worn, because they slow blood from leaving the penis. They do not create an erection on their own, so men who cannot get any erection should see a doctor. FirmTech offers a 30-day money-back guarantee if a ring does not meet expectations.
What is the FirmTech MaxPR?
The MaxPR is FirmTech's tightest ring, priced at $60. It uses the same doctor-designed shape as the Performance Ring, made slimmer and snugger for maximum firmness and heightened sensation. FirmTech rates it 5 of 5 for tightness and 5 of 5 for pleasure, with a wear time of up to 90 minutes and no tracking.
Is an ED ring the same as a cock ring?
They work on the same basic principle: a ring at the base holds blood in the penis. The difference with FirmTech rings is the design. They are made with urologists, use medical-grade, phthalate- and latex-free elastomer, and loop around both the penis and testicles with an adjustable hook-and-latch, so you control the tension.
What does a peno-scrotal fit mean?
A peno-scrotal fit means the ring has two loops: one around the base of the penis and one behind the testicles. FirmTech says this anatomical design spreads pressure evenly instead of concentrating it in one thin band. All three FirmTech rings, including the MaxPR, use this same peno-scrotal design.
Can I use an ED ring if I do not have ED?
Yes, many men use rings for firmer erections and more intense orgasms rather than to treat a diagnosed condition. FirmTech positions the MaxPR for men who want maximum hardness and a more intense finish. If you have a medical condition or take blood thinners, check with your doctor first.
Fit and sizing
How should the MaxPR ring fit?
The MaxPR should feel snug and firm at the base without pinching. It loops around the base of the penis and behind the testicles, and the hook-and-latch lets you set the tension. FirmTech calls it its snuggest hold, slimmer and tighter than the Performance Ring. If it hurts, loosen it or take it off.
Is there an ED ring size chart for FirmTech rings?
FirmTech rings come in one adjustable size, so the size chart is short: all three rings fit up to 5.5 inches (14 cm) erect girth. FirmTech says one size fits 95% of men. If your erect girth is above 5.5 inches, the rings are outside their listed fit range.
How do I measure for an ED ring?
Measure when erect by wrapping a soft tape measure or a piece of string around the base of the penis. If the measurement is 5.5 inches (14 cm) or less, FirmTech rings fit. If you used string, mark it and lay it against a ruler to read the length.
What if my erect girth is over 5.5 inches?
FirmTech lists 5.5 inches (14 cm) erect girth as the fit limit for all three of its rings, so a larger girth falls outside that range. Contact FirmTech customer service through its contact page before ordering to ask about your fit. Purchases are also covered by FirmTech's 30-day money-back guarantee.
How is the MaxPR fit different from the Performance Ring?
The MaxPR is slimmer and snugger than the Performance Ring. FirmTech rates the MaxPR 5 of 5 for tightness and the Performance Ring 3 of 5. Both use the same doctor-designed peno-scrotal shape and hook-and-latch. The tradeoff is wear time: up to 90 minutes for the MaxPR versus up to 12 hours.
How do I put on the MaxPR?
Putting on the MaxPR takes three steps. First, unhook the latch and open the loops. Second, place it so one loop goes around the base of the penis and the other around the testicles. Third, adjust the latch to the tension that feels right, snug but not painful.
Do I put on an ED ring before or after an erection?
FirmTech says its rings are designed to go on when you are soft, so you can put one on discreetly ahead of time. The open hook-and-latch design means you do not have to stretch a closed loop over an erection. Fasten it snug but not tight, then adjust as needed.
Price and buying
How much does an erectile dysfunction ring cost?
At FirmTech, an erectile dysfunction ring costs $60 for the MaxPR or Performance Ring and $275 for the TechRing, which adds sensors and an app. Bundles run from $120 to $499. Shipping is free on orders over $100, and taxes are calculated at checkout.
How much is the MaxPR?
The MaxPR is $60. It can be bundled with RingMate, a vibrator for her that slides onto the ring, for $120 instead of $129, or with the TechRing for $295 instead of $335. The MaxPR is HSA/FSA eligible and has a 3-month warranty.
Why does the TechRing cost more than the MaxPR?
The TechRing costs $275 because it adds built-in sensors, a Bluetooth app connection and a rechargeable battery. It tracks firmness, duration and nighttime erections, and carries a 1-year warranty on electronics. The MaxPR and Performance Ring, at $60, give erection support without any tracking.
Can I pay for an ED ring with HSA or FSA?
Yes. The TechRing, Performance Ring and MaxPR, including bundles that pair them, are HSA/FSA eligible. At checkout you choose Flex as the payment method and answer a short health survey that produces a Letter of Medical Necessity. Your plan administrator has the final say on coverage.
Are there MaxPR bundles?
Yes, there are two. MaxPR plus RingMate costs $120 instead of $129, saving $9. TechRing plus MaxPR costs $295 instead of $335, saving $40, for men who want tracking plus FirmTech's tightest ring. Both are listed on the FirmTech shop.
Is shipping free and discreet?
Shipping is free on orders over $100, and every order ships discreetly. FirmTech uses a plain, unbranded box, and there is no product name on the packing slip or on your card statement. A single $60 ring is under the free-shipping threshold, so shipping is calculated at checkout.
Where can I buy erectile dysfunction rings?
You can buy FirmTech erectile dysfunction rings online at getfirmtech.com, which ships nationwide. FirmTech also runs a where-to-buy map listing doctors, men's health clinics and retail stores that carry its rings. Buying direct gives you the 30-day money-back guarantee and free shipping over $100.
What if the ring does not work for me?
FirmTech offers a 30-day money-back guarantee. If a product does not meet your expectations for any reason, you can start a return through FirmTech's online returns portal with your order number and email. For help, email customer service, which replies within 1 to 2 business days.
What warranty comes with the MaxPR?
The MaxPR comes with a 3-month warranty from the date of purchase, the same as the Performance Ring and RingMate. The TechRing has a 1-year warranty. For a warranty claim, email FirmTech customer service with your order number and a short description of the issue.
Safety and side effects
What are erection ring side effects?
The most common erection ring side effects come from a ring that is too tight or worn too long: discomfort, numbness, cold skin or bruising. These are general risks of constriction rings. Remove the ring if you feel pain or numbness, keep to the listed wear time, and ask a doctor about anything that persists.
How long can I wear the MaxPR?
FirmTech lists the MaxPR's safe wear time as up to 90 minutes at a time. That is shorter than the Performance Ring and TechRing, which are listed at up to 12 hours, because the MaxPR is FirmTech's tightest ring. Take it off if you feel pain or numbness sooner.
Is the 30-minute rule for erection rings still true?
Thirty minutes is the general rule patients are told for constriction rings, according to menMD. The same menMD article says the FirmTech device is made of a novel material that lets blood move in and out, making it safe to wear for more than 30 minutes. FirmTech lists the MaxPR at up to 90 minutes.
What lube can I use with the MaxPR?
Use water-based or silicone-based lubricants only with the MaxPR. FirmTech says not to use natural oils such as coconut oil or CBD oil with any of its rings. FirmTech sells Sliquid Naturals Silver, a silicone lubricant, as an accessory starting at $18.
What is the MaxPR made of? Does it contain latex?
The MaxPR is made of medical-grade elastomer and is phthalate-free and latex-free. It is water resistant. The Performance Ring uses the same medical-grade, latex-free elastomer, so both are options for men who want to avoid latex.
Who should talk to a doctor before using an ED ring?
Talk to a doctor first if you have a bleeding disorder, take blood thinners, or have any condition affecting blood flow or sensation in the penis. A doctor can also check for causes of ED, which can be linked to heart health. FirmTech partners with urologists and men's health clinics listed on its site.
How do I clean the MaxPR?
Rinse the MaxPR with warm water and mild soap after each use, then let it dry. It is water resistant, so rinsing is fine. Avoid natural oils, which FirmTech says should not be used with its rings, and store it somewhere clean and dry.
Does an ED ring block ejaculation?
FirmTech says its TechRing keeps blood in without blocking release, and its rings share the same peno-scrotal design. FirmTech describes the MaxPR as giving heightened sensation and a more intense finish. If you notice any change in ejaculation that concerns you, stop using the ring and speak with a doctor.
Compared to alternatives
What is the best tension ring for ED?
Among FirmTech's rings, the MaxPR is the best tension ring for men who want the tightest hold, at 5 of 5 tightness for $60. The Performance Ring suits longer, gentler wear of up to 12 hours, and the TechRing suits men who want data. This guide is published by FirmTech.
Should I get the MaxPR or the TechRing?
Get the MaxPR if you want the tightest fit and the most intensity for $60, worn up to 90 minutes. Get the TechRing for $275 if you also want to measure firmness, duration and nighttime erections in an app, with wear of up to 12 hours. Many buyers pair them for $295.
Which is better, the MaxPR or the Performance Ring?
The MaxPR is better for maximum firmness and a more intense finish, and the Performance Ring is better for comfort and long wear. Both cost $60. FirmTech rates the MaxPR 5 of 5 for tightness with up to 90 minutes of wear, and the Performance Ring 3 of 5 with up to 12 hours.
Is an ED ring better than pills like Viagra or Cialis?
A ring works mechanically and needs no prescription, while pills work on blood flow chemically. A Cleveland Clinic Journal of Medicine review, cited by RxSleeve, found up to 40% of men do not get a satisfactory response from PDE5 inhibitors. FirmTech says many men use rings alongside other treatments. Ask your doctor.
How is an ED ring different from a vacuum pump?
A vacuum pump draws blood into the penis, while a ring holds it there. Mayo Clinic, as cited by RxSleeve, describes a ring slipped onto the base after pumping to keep the erection firm for up to 30 minutes. FirmTech sells a TechRing plus VaxAid Deluxe pump bundle for $499.
How is the MaxPR different from hard silicone rings?
FirmTech founder Elliot Justin, M.D., said customers wanted a snugger fit that does not pinch like harder silicone rings and can be worn for over 20 minutes without compromising blood flow. The MaxPR uses soft medical-grade elastomer and an adjustable hook-and-latch rather than a fixed, rigid loop.
