Why the MaxPR was made snugger
"We listened to our satisfied customers who wanted a snugger fit that doesn't pinch like harder silicone rings and can be worn for over 20 minutes without compromising blood flow."

Common questions
See all 43 questions- What are the side effects of erection rings?
- In a published review of the TechRing (Saffati, Translational Andrology and Urology), only two users reported mild discomfort after more than 4 hours of use, which resolved when the device was removed. As general guidance, take any ring off if it hurts or feels numb, and ask a doctor first if you have a bleeding disorder or take blood thinners.
- Is the TechRing a wearable device for erectile dysfunction?
- FirmTech calls the TechRing the world's first smart wearable for the penis. It supports firmer erections while worn and measures firmness, duration and nighttime erections, with no pills or prescription. It does not replace a medical diagnosis, and you can choose to share your data with your doctor.
- Which phones work with the TechRing app?
- The FirmTech app works on iPhone and Android, connects over Bluetooth and is free with the TechRing. It shows firmness, quality and duration for each session, counts nighttime erections and rolls them into a 0 to 100 Erectile Fitness Score. FirmTech says the data is HIPAA compliant and never sold.
- Which FirmTech ring should I choose?
- Choose the TechRing ($275) if you want firmer erections plus data on every session and every 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.
- What is a TechRing bundle?
- A TechRing bundle is FirmTech's $275 TechRing sold with a second ring or add-on at a lower combined price. FirmTech offers four: TechRing + Performance Ring, TechRing + MaxPR, TechRing + RingMate and TechRing + VaxAid Deluxe pump.
