Unlike the cheap $15 eBay resetters, the V2 has a metal OBD head and a thick, shielded cable. The buttons have actual tactile click feedback. It feels like it will survive being dropped on a shop floor.

While not a full diagnostic tool, it reads Battery Voltage and Brake Pad Wear sensor status (Open/Closed). This saves you from pulling wheels just to check if a sensor is broken. The Bad (The Caveats) 1. It will not diagnose If you have an "Engine Misfire" or "Transmission Fault," this tool is useless. It has no code reading function for ECU/PCM/TCM. You still need a proper scanner (ISTA, Foxwell, Launch) for that.
