What you get for $60 versus $275
At $60, the Performance Ring and MaxPR give firmer, longer-lasting erections with the same doctor-designed peno-scrotal fit as the TechRing. There is nothing to charge or pair. Warranty is 3 months.
At $275, the TechRing adds built-in sensors that measure firmness, duration and nighttime erections, Bluetooth, the free FirmTech app with an Erectile Fitness Score, a 12-hour battery and a 1-year warranty on the electronics with 2 sleeve replacements. If you only want the erection support, the $60 rings do the same job.
