Customers Reviews
Easy to use, and works like a charm
Before buying the gauge I had some doubts due to the negative reviews here. However, my experience turned out to be much better. The device is easy to use, come with batteries installed (unfortunately a rare thing in these days), and produces good results.
As an additional bonus, being completely automated, and having a self illuminated LCD screen makes nighttime use possible, too.
The only issue (several people also mentioned) is that you have to remove the sticker, otherwise it “always shows 28.5 psi”.
I’d recommend it to every car owner who intends to keep their car in check.
Handy and accurate!
The Accutire MS-4121B was my first digital tire pressure gage. I had looked at them in the past but always decided they were too expensive. But this one was priced right and had the ability to measure up to 150 psi which I needed for high-pressure bike tires. But I was worried that it would perform cheaply as well.
My worries were unfounded as I quickly became impressed with how well it worked. The display is large and very legible and lights up which is handy when checking car tires in a garage that isn’t well lit. The batteries were already installed so it was ready to go as soon as I unwrapped it. It appears to be ruggedly built and I look forward to many years of excellent performance from this device.
