My car tires looked low so I tried to inflate them at a local gas station but failed because the pump failed. Chose this air compressor based on the positive reviews (the bad ones bothered me, but.). Received it today when my TPMS alerted me to low pressure. 7 pounds of air was added to each tire to bring it up to spec, and each took about a minute to reach the desired pressure. The auto shut off when the pressure was reached actually exceeded the desired pressure by 1/2psi, but I'm fine with that. And because of the auto shut off, I forgot to turn off the device. This led me to believe the compressor wasn't working until I realized I had to turn it off and on again for it to start inflating the next tire. Stayed cool even after I bled all four tires. Great item at an incredible price!
