Cooolbuy 150 PSI Digital Tire Pressure Gauge 4 Settings with Non-Slip Grip and Backlit LCD (Black-1 Pcs)

I like this tire gauge, but I wish it would turn off sooner than it does. It's kind of a pain to have to wait the full ten seconds (or more?) after checking one tire before checking the other tires. There is no OFF switch so you have to wait for it to turn off by itself, and that seems like it took way too long to check four tires. Yes, I'm a little impatient, but I finally got all the tires checked but had to let some air out of a few of them, then re-checked those tires, let more air out, re-check them again, repeated the process a few more times (ugh) until I got the tires to be where they need to be. What a long and drawn out process that was. It would have taken much less time if there was as OFF switch on the unit, or at least have it turn off after just a few seconds and not make you have to wait the whole ten seconds for it to turn off. Other than that, it seems fine. Damn, I'm worn out now, lol.

This tire gauge is pretty easy to use and works well for me. It forms an almost perfect seal on the tire valve, allowing for zero air loss when checking the PSI in my tires. Push the button once to turn it on. Hold the button down for 2 seconds to turn it off. Simple as that. It will turn off automatically after 15-20 seconds, but that is just a waste of battery power. How accurate is it? I don't know. It reads slightly different than my old one. But which one is correct? A man with two clocks never really knows what time it is. Ha.

Can't be sure how accurate these are, but they are consistent.Fairly easy to use and read. Just be careful to press-and-hold to clear the readout, then press again to turn it back on – or else you must cycle through three other pressure modes to get back to "psi." There ought to be some other way to keep it in PSI mode.This pair did come with nice little zipper cases to keep extra batteries and the provided extra valve stem caps. The lighted tip is also nice after dark.Despite the issue noted above, I do recommend this gizmo. ***1/2 stars -- If these still work a couple of years from now, I'd go with 4 ****

These have worked well for us. My wife's van has a tire that keeps VERY slowly losing air, so it's important to have an accurate gauge. This is doing the trick, and is helping to keep us safe, especially during long trips. It's got more bells and whistles than we use, and I'm sure they're helpful to some folks, but all we really care about (so far, anyway) is psi, which seems accurate. It's also comfortable to hold while using, and pretty easy to see, even in the bright south GA sunlight (and the backlight has been handy in a number of instances). I would purchase again.

Overall I was disappointed with this purchase. One of the pressure readers didn't work at all, and the other lasted 4 months. One didn't work at all from the package so i decided to follow the instructions and change the batteries. So the picture with the (bad lol) colored circles should be looked at. I followed the instructions given and unscrewed the top half off. The yellow circle indicates the button you have to use to start up the gadget itself...it immediately can fall out of place. In the purple circle are also parts that can be moved around (and cause major issues when trying to align with the other moveable button) where the (removable) button needs to line up perfectly to be functional. When I replaced the batteries the only thing that occurred was overheating the entire product. I tried to replace the batteries in the other gauge and there was no power. This was very frustrating and I DO NOT RECOMMEND. Both of these products were bad.

I only gave it a 4 as it is too early to tell how it will hold up, but so far it works great, easy to read and ergonomic. Nice to keep in your glovebox, maybe I'll buy a couple more for my other truck and other family members as well.

My daughter has two cars so now she has a gauge to put in each car. She has always had a hard time checking tire pressure, so she practiced on all the cars at the house on Christmas day. It was easy for her, she could read the gauge, and she was delighted with this gift.

I think my headline says it all.Bought this to avoid over-inflation on my bike tires, however, the accuracy is questionable, and it's a pain to use.Just use the "pinch" test and save money and bike space.
