    • Great tire gauge
Size: 1-Pack Color: Black
Arrived overnight as scheduled, packaged well. The product is just as described. Simple and easy to use, very accurate. For the price, definitely worth the money.

    • Very Accurate and Measures Quickly
Size: 1-Pack Color: Black
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.

    • Not too sure how long this gauge will last, and check the batteries!
Size: 1-Pack Color: Black
Purchased this in March of 2022. It is now May of 2023. Haven't used this too much, maybe ten times in the past year. Went to use the other day, and it gently dropped (less than a foot) onto the pavement. Did not work after this short drop. Thought that perhaps battery somehow shifted when it hit. Took off the battery cover, and removed the three (3) LR44 batteries. All three of the batteries had started leaking. SInce I didn't have any spares on hand, I cleaned them off and re-installed- gauge now works again. I'll be ordering some batteries. I have an old (over 20 year old) Accutire digital gauge that I carried on my motorcycle- bouncing around for over 80,000 miles- never stopped working, and still on original batteries. This new gauge and the old gauge read exactly the same pressure. I'm assuming they're both right. UPDATE NOVEMBER 2025: The batteries that I put in back in 2023 also leaked (see below) Pros: Has worked well since, no issues. I do like the fact that the display is backlit- it makes it much easier to read than my other gages. The angle of the head also makes it easy to reach the valve on my cars. Cons: The angled head makes it a little akward to use on my motorcycles, as I have to adjust the gage body to clear the brake rotors. I have compared this gage with my two other digital gages, they're all within 0.1 psi of each other, so I suppose they're all pretty accurate. I went to use gage in November of 2025 and batteries were dead. Opened up the unit and tthe (two year old) batteries had also started to corrode. Cleaned up the battery compartment and put in three new LR44 batteries and back in business. I would suggest checking the batteries at least once a year for corrosion and condition to minimize the chance of damage. I keep the gage in an old eyeglass case to protect it in my glove box. I am buying a few more of these as small gifts for my kids for Christmas this year. ... show more

    • Easy to Use & Read. Accurate.
Size: 1-Pack Color: Black
Easy to use & accurate (at least mine was). Much easier than stick type gauge to get securely on tire stem. Fast, so I don't mind checking air pressure in the winter cold.

    • I purchased 3 of these
Size: 1-Pack Color: Black
So much better than the others. Turns on automatically once you place on valve stem. Just set your measurement psi etc….with the tiny button near the top Very easy to read with out having to stand on your head The others would turn off due to the placement of the on/off
