Very Accurate and Measures Quickly
I am completely satisfied with this product. I purchased based on a consumer magazine recommendation. It works great, creates a quick and easy seal on the tire's valve and reads accurately. It's a good value for the money.

Accutire: Why downgraded to one star?
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.

Battery position is critical. Package was substandard.
Gauge is fine and small/handy for car. The shipping and packaging from Amazon was substandard. When I opened the Amazon box the the plastic had separated from the cardboard backing and 3 of 4 spare caps were gone. Battery placement is not easy to understand. No directions on package. Plus/minus markings in battery compartment are hard to see. Beware the batteries overheat if you put in backward.

This fortunately reads psi. It reads the same as another gauge I have and agrees with the car's TPMS so all three must be correct. I have an old version of this gauge from probably 20 years ago and it still works on the original battery. It's very easy to use and is highly recommended.

Accurate as expected

Excelente producto. Se ve claro, es preciso. Solamente a veces la valvulares negra como que si se afloja y se debe de apretar antes de medir. Para que la medición sea correcta se debe de medir en frio. Entonces carga las llantas a 6 psi más de lo que indica el manual. De ahí ya lo dejas la noche y en la mañana antes de partir lo dejas. Manejar con las llantas bajas causa el mayor desgaste y que exploten en carretera.
