Digital Tire Pressure Gauge 150 PSI 4 Settings with Backlight LCD Tire Gauge for Cars, Motorcycles and Bikes with Non-Slip Grip, 2 Pack

This gauge has one job and it does it very very well. The pressure reading agrees 100% with the TPMS readouts in my two vehicles so I'm calling it as accurate as anyone needs short of a Formula 1 race car.Someone mentioned in a review they had to press especially hard to get the device to seal against their valve stem(s) but I didn't find that to be the case at all.If I had to find any fault I'd split a hair over the amount of time the readout stays on (about 15 seconds after taking a pressure reading, 30 seconds if you turn it on but haven't checked pressure yet) but a quick press of the trigger switch fixes that.This is a great value.

Small, in a little velvet bag. So easy to use and read.

I had a pair of these tire gauges for several years when the batteries finally died. They use 3 coin cells each. And when you open them up parts fall out making it very difficult to get back together. they are inexpensive so I bought 2 more. At first I had a hard time knowing what Units the pressure was displayed in. But after a few uses it was not an issue. I have compared the reading to other gauges and they are all within 1 psi of each other. I could not tell you which were actually correct. But 1 psi is goo enough for me.

Read out is very bright, easy to use, and extremely accurate.

I really like the features, however, the two of them don' agree on the readings!

These are usually about 3 pounds off when it works. I bought a couple of these and it seems the batteries die very quickly.

They work very well. These are the second set of gauges that I’ve ordered.

The original three LR44 button-batteries in the "black" gauge lasted a little over two years, with very limited use. The red gauge was stored inside our SUV and has not been used at all --except to test it when it was new, and again when the black unit's battery was low.To replace the batteries, the case must be disassembled by removing two screws with a jeweler's Phillips screwdriver, and gently tugging at the side of the case. One must be careful not to lose the operational plastic push-button, as it just loosely sits in between the two case halves.Now comes the tough part. The three button-batteries need to be pryed out of the battery compartment with a small screwdriver. After testing the old button-batteries, inserting new button-batteries back into the handle becomes a nearly impossible task. I was only able to accomplish that by using needle-nose Vice Grips to press in the third button-battery. (Not sure everyone has a pair or those.)And the final kicker is I was not aware that there was also a coin-battery inside the handle that I did not test. (I became aware of the 4th battery after I revisited the Amazon entry for this product, after replacing the button-batteries, to see if others had reported battery-replacement problems.Anyway, my black gauge is working fine now, so hoping the coin-battery lasts longer than the button-batteries. I actually use the gauge very infrequently because my air pump has a built-in gauge..
