I had a slow leak and it was hit or miss at the gas stations whether theirs worked and felt rushed in using them. This unit is very accurate and sturdy. I keep it in the included storage bag in the car's trunk. A Great Investment.
Pros
Capacity: Does NOT Support truck tires, for instance: light truck tires (LT), heavy duty truck tires or any truck tires.
Cons
The cord can easily become tangled, leading to difficulties during storage and use
