Review on 🚗 High-Performance Digital Tire Inflator: 255PSI Air Chuck, LCD Display, 0.1 Resolution Pressure Gauge. Reliable Heavy Duty Air Compressor Accessories with Rubber Hose and Quick Connect Coupler. Perfect Men's Gift! by Demetrius Holt

This is an easy to use blower and pressure gauge. The gauge will turn on by itself when connected to a tire with pressure, or you can press the button to turn on the gauge. The button also toggles between pressure measurements. The air chuck locks onto the valve, making it easy to inflate tires with hard-to-operate valves or if you are doing other things when inflating your tires. The locking liner was good as I struggled with the tire on the bead to get it into place. There is no dedicated pressure relief valve, but a partial pull of the trigger will relieve the pressure. The sensor is valuable to me because it operates at very low pressures, in my case 8 to 12psi for my zero turn lawnmower tires. The only point of criticism is that the screen is very difficult to read in direct sunlight. I had to dim the screen to even see the gauge was on, and squint and shade the gauge even more to read the pressure.
