It's interesting to see the pressure go up a few psi as the tires warm up. And it is good to catch a slight under-pressure during the winter. The sensors even report the tire temperatures which are displayed in small, non-distracting digits. Plus, this little device is so inexpensive that it could even be replaced every year or two. But wait, there's more! It turns itself off automatically after a few minutes when it senses no motion. And then, it turns itself on automatically when it senses a door opening or closing. And it has a alarm that can be custom set to alarm at a certain low pressure and at a certain high pressure.
