Autel MaxiScan MS300 I really can't say

I really can't say for certain if this item is good or not. I believe I had a false positive warning light. This product did shut the warning light off though. It seemed to have performed the proper scans but there were no codes at the end, and the light shut off, so I assumed that it was a false positive warning. It most likely would have cost me more money for an automotive technician to shut the light off, and possibly tell me something was wrong when there wasn't. It is a good tool to have though in the future if it happens again.
