I have one of these from the late 1990s and it still works great. I like it so much I bought another recently.It died after only 2 days -I tried to read a tire with about 8 psi and it showed "-0.0" on the display. After this, all it would do is show the same thing "-0.0".
So I exchanged it for another one. Sure enough, it worked for dozens of readings, until a few days later I again tried to read a tire with about 8 psi in it. Once again, it will only show "-0.0" after that.
My guess is this is a firmware problem with the new units.
Don't buy disposable units. Pay a little bit more and get something that will work for many years.

Piece of junk. Won't fasten onto the tire's valve stem just releases the air from the tire and doesn't register the pressure (that used to be there). I've purchased several items via Amazon.com, and this is the only one that's been a big disappointment.Read Best Reviews of Accutire MS-4400B Pistol Grip Digital Tire Gauge Here
After buying a lot of inaccurate tire gauges (especially the digital ones), we found a review on Consumer Reports that recommended this one. Bought 3 -all 3 gave the same tire pressure when I tried them out on a tire. Accidentally dropped one on the pavement, then it flipped into the sand/gravel. Blew the sand out of the nozzle and it worked just fine. I don't recommend dropping it into the sand of course, but CR did say it held up well to being dropped and that seems to be true.Want Accutire MS-4400B Pistol Grip Digital Tire Gauge Discount?
I have had this gauge for a couple of years but had noticed significant differences between it and other gauges. Recently I did a comparison between three gauges including a certified master gauge in a tire shop. My gauge was reading 4 psi too low a significant deviation for a 32 psi nominal pressure.Save 43% Off
