No more need to use a separate air gauge after I've filled the tire. I was always afraid that the tire would burst right in my face. Also, my regular car tire gauge read no less than 10psi, so I didn't know how much air I had in my lawn mower tires. I'm glad you have an American made tool. Like the clip-on feature (which works very well). The dial is easy to read. I'm glad it has a rubber collar to keep the dial in place if I drop it. Accurately reading and evaluating the reset button when it's a bit crowded. I checked every tire I had and bled or filled all of them. Nice to use. I also love a black cloth bag to keep and protect in one place.
