Review on TUGOKU Tire Inflator for Car: Portable Air Compressor Pump with LED Light - 12V DC Digital Pump for Car Tires, Bicycle, and More (Black) by Jason Morrison

I've had this tire pump for about a week. The gauge was off from the start (e.g. tire pressure was 32psi, but the digital readout was at least 2psi higher). I need to set it to a higher PSI target for the device to pump air. This doesn't bother me as I have a manual gauge to check later. Kept in the trunk for a few days and tried to use again today but the gauge was completely messed up, a digital readout showed my 36psi tire was not working. over 80psi. As I increased the target pressure to 84psi, the digital gauge now read that the tire pressure was over 90psi, so I gave up. i give it back I just want a basic no frills pump for another car but haven't found a reliable one yet. Everyone seems to suffer from one problem or another. On the other hand my 15 year old inflator still works great, too bad I can't find it anywhere else.
