This is a great gauge. It is accurate and its results are repeatable. I have had two other gauges like this that I have given away with my vehicles when I sold them. Easily fits in the glove box of the car.

Product as described. Easy to use and very accurate. Went shopping one day and everything was fine. On the way home all of a sudden I received the low pressure warning on the dash. I looked at all the tires when I arrived home and none of them looked low. I went to the local fuel station that has free air and set the pump for 32 psi. So I ordered the gauges. Two days later when they arrived I rechecked the pressure and 3 of the tires were over 40 psi and one was at 29. Now they are at 32 psi. I originally bought a two pack then purchased another two pack so I have one in each of my vehicles.

The electronics seems to work well. If you use PSI (the first option) you just press the little button, wait a sec, and go. But the pressure seal is a bit iffy. You have to put force on the gauge against the tire to get a good seal, sometimes even putting your hand on the other side of the tire to avoid leakage. This seems to be endemic to modern bicycle tools. An $86 hand pump I just bought has a similar problem: it either doesn't get on the Schrader stem or is devilishly hard to get off. Maybe it's because everything these days is made in China to metric dimensions, which are a few mils off. Just don't expect bike stuff to work as well as the made-in-USA Schwinn tools of your youth.

This tire pressure gauge works good. Get accurate reading after pushing onto the value stem one time. (didn't have to apply/reapply multiple times like I experienced with other tire pressure gauges)

Accutire: Why downgraded to one star? A new tire gauge should not have its battery wear out after one use and two months in the glove box. I messaged the company at their phone number on the back of the package. They ignored me for 10 days and then proceeded to tell me that batteries are my responsibility. I was future put on the defensive by being told “We’ll replace them just this one time but don’t ask again.” This attitude is absolutely unacceptable, Accutire. When I started researching other reviews I know see this is common. Some even arrive DOA. The guy at the company insisted that my thermometer must have a tiny on button. It does not. I then learned the company added one since their thermometers drain when not in use. Sadly, a HUGE avoid with rude and slow customer service, too. Original review: Accutire vs. Milton vs. Vondior: Which is the best tire gauge? I’m comparing these three since Accutire and Milton are the top two models recommended by Popular Mechanics. The Accutire is also highly acclaimed at the top of Consumer Reports ratings. Vondior consistency receives top ratings here at Amazon. I’m tired of inaccurate gauges and I don’t personally are if it’s digital or an old school pen. Tires are beyond expensive these days and for safety and longevity, you need to get it right! Read on to learn which is best: I’d call this a tire tie between Accutire and Vondier. The Accutire can wash out a bit in sunlight but I love its no nonsense design and consistency. For ease of use, it’s my favorite. One big plus for the Vondier design is that there is no battery needed. It is a simple joy to use and it glows in the dark. The Milton gauge is poorly printed and difficult to read although it is quite consistent. Both the Accutire and Vondior are five star totally tubular tire winners. By the way, the majority of tire gauges are not accurate so choose carefully.

I bought Accutire pressure gage to replace my 20+ year old Accutire gage. Works great
