I've decided to go this route to get length gains going again, and am trying to decide between these 2 devices. Has anyone used both the PenimasterPro Belt system and the Phallosan who can share their opinions on which is better in terms of comfort, ease of use, effectiveness and anything else you'd care to share? I know the PM Pro has the extender too, but I'm more concerned with how the 2 belt systems compare. Thanks for your help!
