It didn't pick up on as many bad O2 sensors that the BlueDriver did. Had to get a refund.

Gets the job done. Easy.

I keep it plugged in and I erase the code that puts my truck in limp mode while driving down the street or on the Freeway. After erasing the code I let off the gas and then back on the gas and I'm cruising on down the road like nothing happened. It also plugs into my sister's 2007 Toyota Matrix. It detected bad 02 sensor. She thought the car needed new cats which almost cost her $1600 from shady mechanic. Paid $40 for 02 sensor.

Read before and after fixes for my vehicles. Saves a lot of time and effort going into parts stores.

And most other cars. Also tried on my 2000 Jeep Cherokee. Simple to use and quick navigation without lag.
