I ordered this because I was tired of adding air and then having a separate pressure tester! It attached easily to my air compressor and filled all 4 tires much faster than the pressure light came on a week ago!
Pros
All in one function: new fully backlit LCD screen, measures psi, kPa, bar and kg/cm²; This tire pressure gauge gun includes an inflator, direct-lock chuck, pressure gauge, hose, exhaust valve, and 3-in-1 digital pressure gauges that can be used to measure, inflate, or deflate tire pressure.
