What a Great Tool!
I was a little nervous about purchasing this gauge because some of the reviewers complained about it being hard to get a reading. Well, I have had no trouble whatsoever using this great little tool. The worst problem I've had is that every now and then I have to redo the reading because I didn't get a complete seal the first time, but I did not lose any significant air and it was no big deal doing it a second time. I'm not good with tools at all and get really impatient fairly easily, so if I am not having problems using this gauge, it's probably because the gauge is actually that easy to use!

The O-ring blows it!
I didn't buy this item from Amazon, I bought it from my local automotive place. But just the same, as some of the others have said, the only real problem with this is the O-ring. It's kind of hard to get a good seal while using this one. It can be frustrating when you're trying to get a good seal, only to find out that when you do get a good seal, that you've lost so much air that you have to do it all over again...as I just did two days ago on both cars and my motorcycle. I finally got to the point where I was just happy to be close and call it a day. The Tirerack ([...]) has what I think might be a better one, but...well, I bought one, and can't find it...which is how I ended up with this one. Needless to say, I'm looking for the one from the Tirerack again.
Good luck on whatever you decide, but if I were you...I might go to my local place and try out one of theirs. Provided that they'll even let you demo it.

Tire Gauge
Bought this gauge for my Son - N-Law and he uses it all the time.

basically useless.very leaky, not worth it
Ok, based on the reviews I did buy this and initially tried this on my honda civic brdigestone potenza tires and guess what the air leaks all the time. there are only handful of instances where in the air doesnt leak.

I really do appreciate the big blue screen and beep when the measuring ais accurate and all that HOWEVER if it doesnt do it basic job without leaving lot of air from the tire all the cosmetics is useless

Keep in mind though I amde 2 trips to different ace hardware stores and I got the 5/16X3/16X1/16 and also the other o-ring smaller than this and still I was not able to get the tire reading properly. The funny thing is after I glued the o-ring in to the guage, it doesnt even allow me to take the reading. Really hopeless

I really recommed to shop around for a better gauge and please do not waste your time and money on this one like I did. I went to wlamrt and bought a 87 cent menchanical one and is works jsut fine...I am all digital and stuff but until I get a good one Iam sticking to this mechanical one which SERVES the purpose

Ofcourse I returned it.

Recommended with reservations
This tire gauge is not always easy to use because you have to be pretty exact when pressing in. If you're off or tilted a little bit, it just lets air out of your tire. There are some useless functions on it, like recording what your tire pressure should be... one can just remember or look on the inner door panel.

Overall, I would only recommend it for casual users because works and who wants to spend that much time shopping around for a tire gauge?
