Bests & Worsts Reviews from Amazon

This analyzer totally performed to my expectations. Very simple and intuitive with minimal need for referencing the instruction book (which is pretty thorough). It accurately diagnosed the cause of my Check Engine Light (error code P0013). Went on YouTube to learn how the replace faulty VVT exhaust solenoid, and after a trip to Autozone for the new part, was able to replace it in about 20 minutes. Rechecked system and it was good to go. Loved that I was able to clear error code from car's ECM memory after the repair. Now I can pass the annual emissions test that is required to renew my next registration here in Texas. Chevy dealer wanted $125 just to connect to the OBD2... then would add parts/labor to that. Paid $65 for the scanner tool, $48 for the part and came out way ahead, plus I now have a scanner to use for any future CEL.
