Fit it right
Fasten the strap snug but not tight. If you are new to rings, start with the Performance Ring rather than the tighter MaxPR.
Safety
Erection ring side effects
The erection ring side effects men most often report are numbness, bruising, discomfort and coldness, usually from a ring worn too tight or too long.
The FirmTech Ring Guide's advice is simple: follow each ring's safe wear time, keep the strap snug but not tight, and take the ring off at once if you feel pain or numbness. FirmTech lists up to 12 hours for the TechRing and Performance Ring, and up to 90 minutes for the MaxPR.

Are erection rings safe?
Erection rings are generally considered safe when used as directed.FirmTech's rings are made of soft, medical-grade, phthalate- and latex-free elastomer with an adjustable hook-and-loop strap, so you control the tension instead of relying on a fixed rigid band. FirmTech states the TechRing is designed and studied for overnight wear.
Anyone with a bleeding disorder, on blood thinners, or with a medical condition affecting blood flow should ask a doctor before using any ring. Mayo Clinic covers ED treatments more broadly.
Safe wear times by ring

| Performance Ring | Up to 12 hours | 3 of 5 (Comfort) |
| MaxPR | Up to 90 minutes | 5 of 5 (Tightest) |
How to lower the risk of side effects
Watch the clock
Stay within the wear time for your ring. Remove it right away if you feel pain, numbness or coldness, or notice skin turning blue.
Use the right lube
Use water- or silicone-based lubricants only. FirmTech says not to use natural oils such as coconut or CBD with any of its rings.

Common questions
What are the side effects of erection rings?
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.
Who should not use an ED ring?
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.
Is it safe to sleep in an ED ring?
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.
What lubricant can I use with an ED ring?
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.
How tight should an ED ring be?
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.
Does an ED ring stop ejaculation?
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.
