While the quality is evident, this is not the best tool for all purposes. It's a good gauge for car and truck tires, but a bit awkward for my motorcycle tires. I can't even fit on a motorcycle rear tire valve. Would give it 5 stars if it was more versatile. Update: May 25, 2015 I have used this sensor about 10 times since purchase and it no longer goes back to 0 and is 15-20 pounds different. Not very good for such an expensive sensor.
