Bests & Worsts Reviews from Amazon

Device will not erase codes. Big disappointment. I didn't need it till yesterday when I tried it for the first time. Waste of money if it won't clear the check engine light from the dash after trying to troubleshoot a problem. I wanted to clear the code and try one solution after the other, but without being able to clear the code how the hell do I know if I fixed anything. Absolute junk
