This is a great tire pressure gauge. This is the second one I own. I bought my first one in 1999. It wasn't until last month when a spider crawled under the bezel and stopped the needle from full travel. I'm ordering another one right away and while waiting for it to arrive I carefully removed the old sensor's body, removed the spider and shaft, when it was reassembled it still worked like new and accurate. I now have two fully functional sensors that will probably last as long as I have.
