Does one constriction ring size fit all?
Certainly not. There are 4 different sizes available. We recommend you try each ring, starting with the largest ring and moving to the next smaller ring, to determine which ring size works best for you. A properly fitted ring will feel snug around the base of the penis, and should allow you to maintain an erection for up to 30 minutes. For best results, make sure the constriction ring is at the base of the penis, as close to the pelvis as possible.
