Bests & Worsts Reviews from Amazon

Don't buy this if you're a professional technician, where time is money, since most of us are not paid by the hour, but by productivity. The display takes a few seconds to power up when attached to a valve stem, then a few more seconds to read the pressure. Even if you power it up manually by depressing the power button it still is painfully slow in reading the pressures. Also, The air bleed valve to let air out of the tire is way too slow, they need to make the orifice larger, takes a good ten seconds to bleed off a few pounds on a small passenger car tire. Also, I notice that when I set the pressure, disconnect the chuck and reconnect the pressure shows about 2 pounds less every time. You're better off with a .50 cent tire gauge and an air chuck or spend about $20 more and get the better gauge.
