Hi. My check engine light has been on for a month now, so instead of taking it to a mechanic, I bought Micro Mechanic. I plugged it into my car and followed the instructions. When it scanned my car, it said "no problems found, safe to drive," so I thought how can this be, my check engine light is on. So I decided to test the Micro Mechanic. I took off my gas cap and scanned my car again and it said "no problems found, safe to drive." Now, how can that be?
So I thought maybe it's because my car is a 2000 and it's too old, so I decided to try it on my roommate's car, which is a 2016. So I loosened the gas cap, plugged in the Micro Mechanic and scanned his car. It also said "no problems found, safe to drive." So I took the gas cap completely off and rescanned it and again it said "no problems found."
So I came to the conclusion that the Micro Mechanic is a bunch of bull. It is nothing but a scam, so don't waste your money on this crap product. I will be reporting them to the BBB.
Bottom Line: No, I would not recommend this to a friend
