It's only been a few days. Went around inflating truck tires, car tires and even a bike tire (up to 80psi). This is my third electric air blower in the last few years. This one looks solid and draws enough amps so I need to get the car running to get the supercharger working properly for it to have enough power. The best feature is the very accurate pressure gauge and the fact that it shuts off at a certain pressure. Easy to set up and remembers the last setting so you don't have to check and adjust every time. There is no need to use a separate pressure gauge or stop inflation to check this as that is done for me. Ideal for topping up tires that tend to lose pressure over months and temperature changes. I am very happy with it and if it continues like this in the future it will be the best inflator.
