This helped inflate my tire from 20psi to 35psi in just under 2 minutes. While the button set isn't particularly intuitive, I love that you can set the pressure, turn it on, and stop when the tire reaches your desired pressure. I was surprised to find the same connectors on both ends of the hose, but this makes it easy to connect to the tire and pump. The 10-foot power cord allows for easy access to any bus bar. It's not as compact as I expected, but it's not that difficult to hide in a corner of the trunk. The good thing is that he includes a bag for all his accessories.
