Review on Measure Your Tire Pressure With Precision: FOVAL'S Digital Tire Pressure Gauge For Cars At 150 PSI by Percy Haulin

Looks and works great! My only real concern is the large size of the unit. It's a big handful; the head is so large that will not fit through my motorcycle tire spokes to access the front & rear tire valves. If you want to use this in confined spaces (bicycles, motorcycles, etc.), you might want another gauge. For car tires, balls and other things with open spaces, it's fine.
