Pros: Precise and accurate Feels solid and well made. Time will tell Cons: A little awkward to store in the glove box - no big deal, just leave it in the trunk next to the spare wheel. Summary: Nothing is as annoying as having 4 different gauges in the tires (2 dials, 1 knob, 1 digital) and none of them agreed with each other, sometimes more than 6psi, or with the car's TPMS system. It's hard to know who to rely on. I finally decided to ditch those cheap sensors and invest in a quality product.
