This is a cool device and powerful enough in an emergency. I found it easy to use and very easy to store in the trunk or even the glove box. The cord is long enough to plug into a cigarette lighter socket and can be looped around any of the four sides to access the tires. The digital touch display and button are sleek and backlit to help in low light conditions. I had another model with a manual pressure gauge that was very difficult to determine if the pressure was correct or not. Another great benefit is that the pressure can be set in advance and as long as the desired pressure is reached the device will stop. This is very convenient as we don't want to check the gauge every time to check the pressure.
