I’ve had a Restorex for almost a year now. I bought a cheaper one to try to wear it for a longer period of time under shorts while doing things around the house, because the Restorex is bulky. What I found with the other extender (which has a double noose design), is that it couldn’t hold the glans as well and kept slipping. I also rarely could get tension to my full erect length, no matter how many rods I added to it. Additionally, the base wasn’t very stable and was a waste of $100. The Restorex really allows you to put tension on and keep it stable. If you have a curvature, it can help with that. I had a small one that I tried to use it on and it didn’t seem to do much, but again, it’s a very small curve to the right (less than 5 degrees). After using it for over 3 months with its prescribed routine, I don’t think I achieved much. I started at 5 3/4” slightly bone pressed EL and stretched length of 6.75”. After 3 months, I sort of stopped using it, but then started up again, with pumping more now. My stretched length is 7.25” now and with a cock ring on, I measure my BPEL at 6.5”. However, I’m also very aggressively pumping now, and that was after a late night of viagra and tequila, so my unit was well stretched out. Still, if money isn’t a big deal, I think it’s worth it, but I don’t think the shortened workout they describe will help as much for PE as it does for Peyrone’s.
