Please ignore the other two users that gave this gauge only one star because it only read 28.5 psi. I find it amusing, but sad, that they didn’t realize that there was a protective sticker on the screen that read 28.5. If you peel off that protective sticker, then you get a nice, bright red backlit number displaying your true tire pressure. This gauge works great! The display is amazingly easy to read, and it is also simple to get a good reading.

Prior to owning this Accutire model, I had a 7 year old Accutire digital gauge that finally broke. WIth that old model, it was much harder to get a reading without air leaking out. With this new model, if you just push the gauge straight into the valve stem, you easily get a solid reading without leaking air. The old model’s display wasn’t backlit either, and I was truly impressed with the large, bright numbers on this new model. I’d highly recommend getting this gauge, as it has all the functionality you need, at a very reasonable price. I like having accuracy to 0.5 psi, and I never use non-digital gauges unless I have no other choice. I also tested this gauge with back-to-back measurements, and it was accurate every time. You won’t regret this purchase…

While this product works fine, and is accurate, it uses (3) A76 watch batteries. That’s a lot of batteries. and the batteries generally only last about 6 months. I have to pay $2 ea for the batteries. Total $6 each time. That’s $12 a year. and the unit only cost $8.
Maybe a unit that uses lithium or other long-lasting batteries would be better.
