I tried it until there was nothing left to do to make it work.Cheap and worthless.
Good
I wanted an inexpensive tire gauge and this proved to be a good option. So far I am satisfied with my purchase.
Handy tool
Very satisfied with the tire gauges. My wife has carried one of these in her car for several years. I bought several more in December for Christmas gifts and to put one in every car. The pressure readings match well enough between the various Accutire gauges, a mechanical gauge and the built-in tire pressure sensors of our GM car.
tire guage that works
Got just 1 of these to start, liked it enough to get one for each of our vehicles. Then, after only 5 years, 1 malfunctioned and it was somewhat of a search finding a replacement. So ordered 2 to make sure there is a spare. only reason it is 4, not 5 star rating is that the one malfunctioned!!
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.
