It excels in compatibility, supporting all major OBD2 protocols and working with a wide range of vehicles from 1996 onwards, including various US, EU, and Asian models.

Functionality-wise, it reads and clears error codes quickly, provides live data, and displays freeze frame information, making it a useful tool for both car owners and mechanics.
