Works Like A Charm 
2008-10-06
I've always had trouble getting a good reading with manual tire gauges. This one is easy to use, and the display is big enough to read even while juggling the air hose, a handful of quarters, and the valve cap.
Okay, but not great

The price was right so I bought a few of these. I do not find them very easy to use. They have to be perfectly lined up to get a reading and not let air out of the tire. The display is not that readable either. At the price, they are okay, but not great.
Nothing Fancy. . . It Just Works 2008-08-03
I've owned this item for a few months now, and used it several times, all without a problem. There's nothing "fancy" about it, which I like. It's a straightforward tire gauge. I've been very happy with my purchase.
A must have for everyone.

I have a small compressor at home, and it has a built in pressure gauge that I used to believe. I got this, and realized that the pressure gauge in it was off by up to 5 PSI, which makes a huge difference.
Pros: Tiny, Light Weight, Accurate, Inexpensive
Cons: As other reviewers said, you need to put this onto the valve straight on, and press hard. Otherwise, air leaks out. I over-inflate the tires, and then use this to let some air out until I get to the correct pressure.
Overall: I have used this for over three months, on all of our families cars. I have never fully deflated a tire with this, and it has never taken me more than three tries on a valve to get it to seal. For the price I think it is worth it, and I would definitively buy it again.
Works well as advertised 2008-07-20
Like the title says, works well as advertised. Cheap price and quite small, it's got a special spot in my glove compartment. The digital meter thing is easy to read in daylight. Also, it'll take a bit of practice but to keep air from flowing out the tire, it's gotta be put on a certain way--straight so it can be accurate. Hope you found this review helpful!
Hey, it works. 2008-07-04
Keychain Digital Gauge in black with larger display
Lovely Product 2008-06-26
Small lovely product. Does what it's meant to do. Can easily be carried every were you go. Love it.
nearly impossible to use without deflating tire 
2008-05-27
The gauge has to be e-x-a-c-t-l-y lined up or else you won't get a reading. Worse yet, you'll deflate your tire. I've lost 5psi out of a 30psi tire once trying to use this.
Thought this was just a cheap china knockoff that would break.. 2008-05-27
This thing has seen better days since i bought it around a year ago. it was five dollars, and i knew it would only last around two weeks, but that's all i cared about. i've sat on it, burned it, threw it with my keys on the keychain, and it just won't die after i have lived with it for that long. i don't know what kind of magic dust they put on these things, but it does what it says it does, and it is surprisingly accurate (within .5 LB) so do yourself a favor, don't buy a $15 tire gauge at pep boys. order this and it'll treat you right.
Accurate and inexpensive 2008-05-10
I got this to use with my bicycle, which requires anywhere from 35-80psi.
I have a more expensive precision gauge for work on my motorcycle but it didn't have the range I needed. I figures this would be an inexpensive solution.
I have to tell you I am surprised that such a small inexpensive gauge is so accurate. It had identical results as my precision analog gauge in all tests I did.
The only issue I have is that it takes a bit of getting used to in order to get a proper seal with this digital gauge. If you hold it off angle from the valve stem even by only a degree or two you will not get a proper seal. Like I said though, you just need to do it a few times to get used to it. Other than that it's outstanding!
Small, lite, accurate reading to 1/10 of a PSI, and it powers on and off by itself.
In fact, I may just have to order a few more of these so I have one for every vehicle.
