Query: Pressure Release Failed After First Use

Right out of the package I used it first on the front tire of my bike and the gauge and pressure release worked fine and then I used it on the back tire and the pressure gauge read zero. The release malfunctioned after the first use, so the dial would go back to zero right after you pulled the gauge off the tire. I put it back in the box and returned to Amazon.com immediately! I do NOT recommend!
