I bought it for my husband as a gift. I think we both benefited from the purchase! It's easy to inflate and measure your tires and you can set the pressure and it will turn off once the tire reaches that pressure. The keys are larger to make them easier to read. It plugs into a car charger and has a cord long enough to reach the tires in my car, but I haven't tried it in our truck yet. My husband says it's a lot easier than the pump and meter he used so it will do a lot of good.
