What is the difference between the TechRing and the Performance Ring?
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.
