I had the same problem as Peter, the gauge would read 28.5 on all tires and even during “calibration”. No display movement,
a constant 28.5. This must be a comman defect.

I’m religious about my tire pressure. I keep a pressure gauge in each of my vehicles, along with a manual tire pump. Moreover, I know what to look for with devices like this, and all my experience told me this one looked like a winner when I decided to purchase it.
First thing I notices was difficulty in seating it on the valve stem. I lost 5 psi. before I got a complete measurement. I could have gotten used to that, but…
After about two days of using this product, it had a change of heart, deciding that all my tires, on all my cars, had 28.5 psi. No car of mine keeps pressure that low, so I let it shut down and tried it again a few times with the same 28.5 psi result.
Now I have nailed it up on my “wall of shame” of all the cheaply-made and low-quality car accessories I have come across.
My recommendation: take a pass on this item, and buy one of the generic $7 ones from your local dept. store auto section. I bought one of these two years ago and have used it on a weekly basis ever since with great results.
Your experience may be different, but mine doesn’t work correctly.

Delivery was prompt. Product received was brand new. Great buying experience overall. Will definitely buy from Amazon.com again.

I would not recommend this product because it is not accurate. a digital machine like this should keep its measurements at all time but this one for some reason keep changing its measurements depending on the weather. When is very cold, it gives you the wrong preasure. I would stick to the simple non ditital tire gaufes.

What is the problem with these gauges? Naturally I peeled off the label first, and, on eight tires on two cars, it would only read 28.5 PSI. Then I did a Zero Reset several times; now it reads anywhere from 25 PSI to 29 PSI on tires I know to contain 34 PSI.
I make sure it is seated properly, and there are no air leaks.
Maybe that’s why it is being sold for $6.49!
