Review: Great Adaptors - These adaptors work very well. The threads are deep enough and long enough to make good, solid connections. And they look good, too.
Review: won't pump up, pump runs a few seconds and quits. Easy fix. - When I got it, I charged it and it wouldn't work. the punp would run for a few seconds and quit. I opened the middle where the stainless tube screws onto the plastic handle of it and found the check valve was upside down. I flipped it, it fell into position, the pressure from the pump locked it into place. Easy as changing batteries in an old flashlight. And now it works great! It has quite a kick to it, about like a .22 rifle. It was an easy fix, no tools required
