The Moroso 89560 Tire Pressure Gauge lasted almost one year from the date of purchase. Over a number of months I began getting different tire pressure readings each time I checked, often one right after another. I cannot in good conscience recommend the purchase of this gauge due to the fluctuations in readings. I discovered that the Moroso Gauge was consistantly off by 2-3 pounds. I have ordered a liquid filled tire pressure gauge from Longacre. It is supposed to be very accurate. [Moroso 89560 Tire Pressure Gauge, Dial Type, 0-60 psi]].
