I like this cartridge! It actually sticks to the valve stem! I even turned the hose upside down to try and pinch it off. It stays there until you intentionally loosen it. I replaced the cheap chuck that came with my tire inflation tool with this one. The chuck I previously had on the tool lasted maybe the first two times I used it. After that, every time I wanted to inflate the tire, I had to go behind the tire and hold the cartridge. Old bones, old back, old knees complain about it every time! LOL It just snaps in and stays. And the tire tool also reads the air pressure. So the work is done quickly and almost painlessly.
