First things first. How well does it measure PSI correctly? It's fairly accurate as I've compared it to a few other gauges, but it only reads correctly about 95% of the time. I had several times when reading was far away. So I turned it off and on again and then it showed the correct pressure again. I store it with the batteries upside down as it looks like it could easily turn on inside the case if some pressure is applied to it. I like everything about it except that the screen is very easy to scratch. I'm usually very careful with my stuff and this tire pressure gauge is already so scratched it's hard to read the display and I'm not even sure how it happened. It's been 3 years now and it still works great and I haven't had any more accuracy issues.
