Negative Positive
Title: inaccurate
Review: I've had the gauge a couple years and thought it was working well. One day I checked my car tire pressure and the gauge indicated the pressure in all tires was in the mid 40s (should be low 30s)! I figured a mechanic had over inflated them, so I let some air out. Several weeks later my mechanic checked my pressure and said my tires were under very underinflated (mid 20s) and he filled them. When I got home, I checked again. Sure enough it read in the mid 40s. I checked against another gauge and which read in the mid 30s - which is what the mechanic set them to. Bottom line: this gauge is now reading about 10 psi too high and is effectively broken (I'm not entirely sure it ever worked correctly.)
Is the review positive or negative?
