I bought this because of the auto-off function, which works great by the way! I've used it many times since I bought it (about once a week) and the only thing I've noticed is that it heats up/gets hot after use. The cable is hot closer to his body, and the valve hose that pumps air is hot when I remove it from the tire. I love that I can install it and do other things like cool the car down instead of standing next to the tire waiting for it to show the psi I need to stop at. So far it's working like a charm.
