This digital tire pressure gauge is really nice to have. I keep mine in the tools that I carry at all times in the trunk of my car. It has a light so you can easily read the pressure. It has 4 ranges 0-150PSI / 0-10Bar / 0-10Kgf/cm² or 0-1000KPA and 2 modes for Car/truck, Bicycle. It also has an auto off mode that after 30 seconds of inactivity it will turn itself off, that way the battery will not die as soon when I keep forgetting to turn it off! It has an ergonomic handle and non slip grip. What I like the most is the company gives a 100% lifetime warranty on it! That gives me peace of mind and the product works great!
