Mine is cursed, so far I've killed 2 boards and now blown out 2 QEV's for totally unknown reasons. I also have the old style back cap that doesnt require cutting but occasionally shoots off the back and hits you in the face. This new cap setup is much better. When I had it working irrc I shot a hopper out of a couple hundred psi from my 70/45, with a slight leak cause I kinked a hose installing it. I like it, shoots good, totally worth the 75 bucks.
