These valves are nice because they give you a bit more control over the gas going through your gun. Very handy for a tinkerer who wants to check for leaks, also good for preserving the lives of your tank o-rings. I don't think having this valve over a pin valve would save much air since you still have to shoot the excess air out. You can't really find these valves for any less than $20, which seems a bit too expensive to me. One can always preserve o-rings by unscrewing a tank a little bit, then shooting out the excess air, an on/off isn't required.
Decent product, but there's too much hype surrounding it that just doesn't make sense. In the long run you're better off just keeping the stock pin valve, why spend money where it isn't necessary?
