This is the second one we have bought. Considering how much it costs, it's excellent. The ability to set an auto shut-off makes it easy to use hands-free - also great because you can sit in the car without worrying about over-inflating your tires or impacting the elements when inflating. It pumps as fast or even faster than my $70 premium unit, but it's quieter and won't burn you if you touch it. The digital gauge is accurate to within 1psi compared to tpms and other serious racing gauges I have. The only downside is the light isn't very bright, but if you don't have the right flashlight it will do the job.
