Review on WDS Digital Tire Pressure Gauge - 150 PSI, 4 Settings for Car Truck Bicycle, Backlit LCD, Non-Slip Grip - Multiple Tools Included - Silver Black by Glenn Cartwright

This gauge/multi-tool is certainly handy and affordable, but unfortunately the included flashlight has a flimsy switch that can easily be hit in the glove box. This happened to me and completely drained my battery. As for bonus points, there doesn't seem to be any low voltage protection circuitry and battery acid leaks all over the unit. First of all, the flashlight is incredibly weak, so completely useless. Because of this, I removed the switch entirely. I shoved a lockpick under it and tried really hard - I jumped out right away! The switch (copper) can be seen below - I'm happy with that so far as it would be extremely difficult to accidentally turn the light back on.
