| Customer Reviews: Average Rating:  Rating : - 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. + See Full Customer Review |  |
