I've installed countless Golf Pride Tour Velvets myself w/no problem for ages. Can do it without a vise, just need tape and solvent. Decided to try Zero Friction, thought it would be the same, tried installing 5 grips, each of them got stuck 1/4 way, had to rip them off. Tried no tape, oil, ripped up my hands doing so, put up quite the sweat. As you can see in the photo, the one on the right, clearly wider, is Golf Pride. The Zero Friction is advertised as .600. They're on sale @ Rockbottom Golf. Ya get what ya pay fa so beware if you're thinking of these. Gonna bring it to the local store, see if they can install it. I wonder, if I had an air compressor and that Pure Grips attachment, I could have installed it. Using up all my tape and solvent before I go with Pure Grips. Tape and solvent is getting real old though, might just chuck them. And the Golf Pride grip on the right - slipped right in - took me 30 seconds to complete the install.
tl;dr - Zero Friction - not so aptly named. Friction Galore.
