What is the MaxPR?
The MaxPR is FirmTech’s tightest erection ring. It keeps the original peno-scrotal design, looping around the base of the penis and behind the testicles, but is slimmer and snugger for extra pressure. Firmer pressure at the base holds blood in place while you wear it.
Like every FirmTech ring, it uses an adjustable hook-and-latch strap and medical-grade, phthalate-free, latex-free elastomer. It has no sensors and nothing to charge. FirmTech rates it 5 of 5 for pleasure (Most intense).
