I just got my new Azuno gauge/pneumatic chuck and I'm already in love with it. The other day I inflated my tires with a sticky dipstick that had to be pressed against the tire valve. Printing has always been weak, but I did my best. I checked them again when my new gauge arrived and it received a great seal and also found that three of my tires were over-inflated between 1.5 and 5psi. Depressurizing was very easy; All you have to do is press the button on the meter. Then an under-inflated tire was inflated by pulling the trigger on the pressure gauge. I find that the gauge reads the pressure in 0.5 psi increments. It's close enough for a government job and certainly close enough for me. It was the best gauge and air chuck combo I have ever used. My only regret is that I didn't find it sooner. I'll update this review if it doesn't last, but it seems very durable.
