This pump was bought after two others were returned. Unlike the other two, it filled my tires quickly, the digital pressure gauge matched my car's tire pressure readings. The only major downside is that the power cord needs to be at least two feet longer, and the hose from the pump to the tire can also be a foot longer. I bought a 12V extension cord so the power line is shorter. Based on others I've bought and tried, this one is the best so far, with the exception of the length of the cable.
