What reviewers mention most
Performance Ring and MaxPR reviewers talk about simplicity and fit: the Performance Ring as comfortable and easy, the MaxPR as noticeably tighter. TechRing reviewers focus on the data, including nighttime erection tracking, trends over time and sharing results with a doctor.
One longer review notes that wearing the TechRing overnight took some getting used to and that building up to it helped. These reviews come from buyers on FirmTech's own site, so read them as customer experience, not a clinical result.
