Bests & Worsts Reviews from Amazon

A very simple to use pressure gauge. You just plug it in and it tells you the PSI. I put it in the trunk near the spear wheel just in case. Happened to me once when the pressure light in my car went on and I had to search for a gas station plus a one with a working pressure gauge. Not doing that anymore. It's small and doesn't take any space and the display is easier to read than those mechanic ones the raises a cylinder by the amount of pressure.
