Review on Accurate and Reliable Champion Sports Pressure Gauge: Ensure Optimal Performance by Greg Floyd

I purchased this product to help with my daughter's science project. She wanted to know how PSI affects ball bounce height. The problem was that it worked when we first tested it. By type I mean the needle was moving but I didn't trust the reading because the pressure should have been higher, we just filled the balloon with an air compressor. Then, when the sensor was used, the needle broke and entered the device. Completely packed! ARG! My suggestion, which we later made, is to buy a cheaper reader that looks like a car tire pressure reader. The one I received had the option of using pump needles as a replacement.
