I really want to like this thing. The vacuum pump gives me no problems and creates a real vacuum. My problem is the valves, you can tell they're just cheaply made when you turn them. The big problem I have is the stopcock on the yellow fill line. When I first used it I could feel the rubber inside rip as I rotated it and now I keep fumbling with this thing because it leaks a little and then clogs up and I keep rotating it back and forth to do this. Fill in coolant. I'll replace it before I use it next, but it's just a bit annoying to take a bad valve straight out of the box and know the rest doesn't feel strong either... I'll probably just have one buy some fittings and redo whatever I can without damaging the high pressure hoses. just annoying. I wish the gauges were a bit sharper and had better resolution (the underside goes up to about 200psi or something...why?). However, I am happy with the pump.
