Query: Terrible Product

Received my gauge two days ago and hooked it up. Readings were way off, when compared to a digital gauge, but the worst part was the actual valve. Clumsy and flimsy, and with the rims on my truck difficult to use. Purchased a classic brass tire inflator with a sliding PSI gauge (like they have at most service stations) from The Home Depot for $16 and it worked much better. Buying this product was a mistake.
