Customer Reviews

Old ones were great -- new ones don't work
I have one of these from the late 1990s and it still works great. I like it so much I bought another recently.

It died after only 2 days -- I tried to read a tire with about 8 psi and it showed "-0.0" on the display. After this, all it would do is show the same thing "-0.0".

So I exchanged it for another one. Sure enough, it worked for dozens of readings, until a few days later I again tried to read a tire with about 8 psi in it. Once again, it will only show "-0.0" after that.

My guess is this is a firmware problem with the new units.

Disposable
It worked fine until the battery died. Then I found out that's designed to be disposable. I actually disassembled the unit and got a battery from Radioshack, but oh surprise, the unit didn't work anymore.

Don't buy disposable units. Pay a little bit more and get something that will work for many years.

Digital Tire Gauge
This tire gauge only works about 20% of the time. If you test the same tire several times in a row (good luck) it will give different readings 80% of the time. I'll stick with the mechanical tire gauges in the future.
