Defective gauge

The scale behind the gauge needle warps up, and jams the needle, which will not advance as the pressure increases. In my case, the gauge stuck at 20 pounds when a separate tire gauge said 55 pounds. If you don't notice that, easy enough to do in dim light, you might seriously over inflate a tire. The unit was stored inside, not exposed to damp. Too dangerous for me to use. Trashed it as I think it deserved. The chuck leaves quite a bit to be desired. Next time, I might try a digital gauge. The battery might run down, but no reading is better than a bad reading.
