This is the summary of consumer reviews for Accutire MS-4021B Digital Tire Gauge. The BoolPool rating for this product is Very Good, with 4.10 stars, and the price range is $10-$15.

Accutire MS-4021B Digital Tire Gauge measures pressure in 0.5 psi increments. Attaching it to the tire valves is made easier by the angle of the gauge and handle. It is very solidly built and durable. This is an excellent tool for any glove compartment to use when needed. The screen is easy to read, the handle is easy to hold. The display is large and very legible that lights up when checking car tires in a dim lit area. It is so much nicer than using an analog gauge and guessing the accuracy. The pressure reading does automatically shut off soon after a reading, but it stays displayed and backlit long enough to read it easily.

Users complain that it stops working after replacing batteries. Also, it does not make a good seal with valve system and air leaks while checking pressure.

Overall, it is easy to use, gives consistent readings, and readings are easy to read. This is a reasonable gauge for a reasonable price that is far better than the old fashioned metal analog variety.
