Now it's my favorite tool and I have a lot of tools. I'm not a mechanic either. In the past, inflating tires with air by moving them back and forth with an air chuck and tire inflation tool was always tedious. The dial is nice, big, and easy to read, and it's now really fun to check and bleed the tires on my family's cars and bikes. Sounds weird I know, but with this tool it's so easy, it's true! :)
