I've used the noose head on andropenis for too long. The pain got so unbearable, I actually quit for nearly 4 months and lost .5" in size. I did a quick search on the forum and found some people used a vac head on their andropenis model. I was wondering how the vac piece works. It sort of looks convoluted, because of all the equipment it takes to put together. Can someone give me a direct link on what I want to buy? I have all the extension rods I need. Maybe with your help I could save some $$$? Thanks everyone.
