Although I thought spending $50 on an air pressure gauge would be too much, I'm glad I spent my money on this pressure gauge. This sensor is extremely accurate for everyday use on conventional cars and motorcycles. While cars shouldn't be too precise, motorcycle tires should be. 10 psi and you could wear out your tire prematurely. Aside from being very accurate, there is one luxury item that comes with this product and that is the exhaust valve knob. That's a great feature, it's great. I will intentionally inflate my tires a bit so I can use the exhaust valve to bring them back up to exact factory specs or desired PSI. No more bleeding a valve and then measuring again and again until you reach your desired PSI, now it's just a push of a button. If you decide to purchase this tire gauge, you MUST purchase a protective case for the tire gauge (Moroso 89590). ). Remember that this is a precision instrument and will be subject to minor shocks. The rubber armor on top of my gauge gives me a big chunk of sanity.
