Accutire MS-4004B Digital Tire Gauge with Back Lit Display and LED Lighted Tip

• Great styling and durable aluminum construction, includes a handy storage pouch
• Accurately measures 5 to 99 PSI in 1/2 pound increments
• Powered by a lifetime lithium battery, automatically shuts off when not in use
• Large backlit LCD display and LED flashlight tip
• 5 year warranty

I bought this gauge about 4 years ago. I find the readings to be accurate (from low to high readings) I no longer have to have a 0-10 psi. gauge and another 0-100. The LED light button is a bit in the way when applying pressure to the schrader valve making the LED to illuminate. I find the reviews somewhat misleading because they claim that the battery is NOT replaceable. However, they are most assuredly accessible. After Removing the small phillips screw on the back, wiggle back and forth while pulling on end and the battery compartment will just pop off, revealing two stacked (CR 2032) lithium batteries. The battery housing has polarity stamped so you know how they orientate once replaced. I hope you find this review helpful and not mistakenly throw away a perfectly good digital gauge because of what some have stated as being "permanently installed".

I've owned one of these since 2004. It sits in the glove box of our Sienna, which needs its tire pressure checked weekly otherwise the tires wear really fast (another story). The gauge takes a little getting use to in order to get a good seal over the stem, but once you get to know how to do it properly, it works everytime. I like the fact that mine came in a case, so it is nicely packed away in the glove box.

The backlight readout is great. You can check in low light places (like my driveway) and still see the numbers clearly.

Too bad this is more expensive than the Accutire MS-4201B, otherwise I would buy a 2nd one of these.
