This is a good little machine to use in emergencies when seasonal temperature changes cause pressure fluctuations in car tires. It is also convenient for inflating basketball, volleyball, float, beach ball, etc. during sports and vacations. In general, the machine is good and it's not bad to have one in every car in case of emergencies. In a real flat or leaking tire situation, this can save you the hassle of changing a flat tire or potentially save you a wrecking bill.
