Autel MaxiScan MS300 Works Well

If you want to know why your check engine light on this is a nice tool to have. It its easy to hook up and will spit out a code telling you the problem. Simply look the code up in the booklet and it tells you what is wrong. I don't fix cars myself, but I can generally tell the difference between something major that needs to be looked at by a mechanic right away and something minor which I can hold off on. For that purpose, this is a great tool and well worth the $30 that I spent on it.
