PosTVac Mach Ring

PosTVac Mach Ring has a thick center, creating an evenly dispersed tension and comfort over a wide area.

Following my radical prostatectomy procedure in 2018, I’ve been using the Osbon Esteem Manual for 4 years now, as part of my rehabilitation. The device is easy to use and has become a part of my daily routine.

The Osbon ErecAid system has changed my life (and my partner's). I did not respond to oral pills, so vacuum therapy with the Osbon was a saviour.

We’ve been referring patients to the Osbon systems for over 5 years now and the feedback has been incredibly positive. They’ve become an integral part of our sexual health product line.
