Love the gauge, the flexible neck and the way it works. I bought the 100psi version for my cars that run at 50psi as these gauges are usually most accurate in the middle of their range. Remember that the accuracy of this gauge is + or - 2 psi. So if you test it and expect it to be correct, it might not be. I think a 2 PSI option for less than $20 is acceptable. I bought a few more of these pressure gauges as they would make a great Christmas present. I have found this pressure gauge to be much easier to use than my old gauges and have therefore checked tire pressures on all my vehicles more consistently.
