Easy to use, reads codes but only if they haven't been cleared by someone else. If worn out by the mechanic and they don't reset themselves, you'll have to drive about 50-100 miles before they show up again. But on average it's a good little tool scanner to teach you the basics. It's not $5,000. The scanner that Scotty Kilmer uses but it costs me a few bucks because I hate being scammed and we get scammed by a lot of people!
