Works well for what it is but not tremendous quality. One of the EPauto nameplates fell off when I took it out of the box. Also, the bag is way too small. It's nearly impossible to get the unit into the bag so be careful as the plastic handle snapped in half when I was trying to press it into the bag. The best part of the unit is the digital gauge and ability to preset your desired PSI and it fills up to the desired PSI fairly quickly.
