Actually better than I expected. Everything seems fine except that the main body and threads are plastic (as you know most plastics in a California garage become brittle after years at 110+ for several months). I like two features: Tire pressure after connection to the tire nipple. except when pumping air. It has a useful button in the center of the stem, just below your thumb, that deflates the tire. Very easy and simple. I don't like two features: - The short rubber hose doesn't rotate. So you can't position them at a comfortable angle, you have to rotate the whole pump to find the right angle to connect to the tire nipple. It will NOT show any pressure when you pump air. Instead, the sensor will bounce across the range until the pump is stopped. So you have no choice but to pump a little, then stop, then keep pumping, and so on.
