Their one product I've bought is their RoP... (had to replace supras after it vanished while running...and theirs is cheap. Both contexts of cheap)
Its similar, thin soft silicone tubes. Had to superglue the tubes on soon after purchase. Got lengths figured and trimmed within a week and had to glue because they popped off quickly.
I was just hoping people could provide links to more intense stretches than the "newbie" stretches. I remember back in 2010 (before quitting pe) there were tons of manual stretches that I cannot seem to find anymore. I think there was one call a Uli or something and horse squeeze I think, but now I cannot find hardly any manual exercises anymore...
