Using this tire inflator on two different vehicles. I like that this device is small (smaller than it looks) and doesn't take up much space in the trunk. It's not a quiet inflator, but it works quickly and feels well built and reliable. My only gripe is that the power cord isn't neatly stored inside the unit and I would have preferred a stronger metal bus clip. The plastic block works well, turns quickly and easily. Otherwise a solid value and something I'm sure will be useful for years to come.
