The latch (for lack of a better term) works fine when not on the valve stem, but when I try to latch it on the valve stem it refuses to move. It's useless if it's not attached properly. Possibly user error, but I've tried multiple times.
Pros
US Standard Thin Thread: 0.305""x32TPI latch just like the threads on standard tire valve stems. Screw the adapter end of the air tool onto the original inflator hose, squeeze to clamp the adapter head onto the tire valve, start the inflator for fast, leak-free inflation.
