Review on Kungfuren Car OBD2 Scanner: Check Engine Fault Analyzer for OBD2 Protocol Cars Since 1996 by Josh Clifton

Thanks to the many DIY repair videos on YouTube, this product usually pays for itself after the first DIY repair. My dreaded check engine light came on. I plug this unit in and after a few seconds I get an error code saying it would have cost me at least $400 if I had gone to the dealer or mechanic. Bought for $32 and 25 minutes under the hood old, refurbished condition. Two weeks later the dreaded check engine light came on and another error code popped up. A repair at the dealer would have cost me 700€. $82 purchase and 20 minutes under the hood, and viola again, the check engine light was gone and my car ran like new. I am far from mechanically inclined and have been able to do DIY repairs after using this diagnostic tool.
