I really wanted to like this gauge. I bought it to check the pressure in my wheelchair tires when I fill them up. My tires need 120psi to perform at their best. It worked great the first two times. I was going to use it tonight and the handle in the gauge head that presses on the valve stem to release air for reading broke off rendering the gauge unusable. Kinda rubbish and waste of money. The worst part is that I don't have a return period, so I can't replace it unless I want to spend the money again. Will not happen. Stay away from it.
