For my first top-grade scan tool this one served a great purpose for my garage.

Super valuable for vehicles 2004 infiniti, 2007 Dodge, 2001 Elantra, 2013 Lexus C400, ext.. worked ok. I was able to resolve EVAP issues. BIdirectional Testing and determine what root causes. This tool also allowed me to scan other modules, retain a history of my vehicles and save data.

Out of all 7 vehicles, this does not reset codes for MB 1997 E420, ABS/ASR this tool has 2 options for MB 34 pin or 16 pin.. 16 only scans the engine. No breaks, tranny, etc. I have a wheel spend sensor issue was unable to pin point the right sensor.

It has performed flawlessly. It's compatible with the overwhelming majority of vehicles made on this planet, and has a whole host of features including not only live data but resetting control modules, programming keys, and a long list of actuator tests. Battery life is also impressive with the need to recharge being infrequent. Updates to the software are frequent and useful.
