This is the best tire gauge period... how do I know? I have 4 of them, they all give the exact same reading, try that with 4 tire gauges of any other make or model...
Much more accurate pressure reading over pencil guage .
Useless, the gauge was not working properly and I compared it with a gauge at the tire center and It was way off. Got another gauge that gives the correct reading and threw the Sears gauge away.
This tire gauge is accurate but does not have long lasting lithium batteries. It contains only three silver oxide batteries LR 44
