This is a great, no non-sense tool for a gal like me who doesn’t know much about cars/tires and doesn’t necessarily have the time and patience to go to the gas station to check in tire pressure, with two screaming children in tow. It is intuitive to use and easy to handle. It has a pretty good weight to it, which makes it feel more reliable. Occasionally I’ll get two different readings in a row, but only slightly off from each other. Overall I’m glad to have it in my glovebox.
