Review on Advanced Digital Tire Gauge for Cars and Trucks - Slime 20475 Elite with Large, High-visibility Display by Chris Russell

Pleasantly surprised at the moment. Really easy to attach and detach the valve stem without letting in a lot of air. And so far I can read it well, day and night. Good for the elderly who otherwise need reading glasses (they are not needed with this sensor). My only criticism of this design is that you have to be careful about placing it on the center console or in the glove box where the activation button can be accidentally pressed while driving on the road. It turns off after a few seconds, but you don't want to accidentally turn it on often. I try to place mine so the button is facing up and nothing else can hit or press it. This sensor seems to be within 1/2 lb of the PSI reading compared to 2 or 3 other sensors I have, so it's close enough for me. Anyway, I'm not sure which one is really accurate.
