Returned Due to Errors and Odd Navigation
The exit button does not step back but returns to the main screen, and every start requires an authentication check. Reading Mercedes data produced incorrect values, such as a freeze frame showing a speed of 257 and a temperature of -58. After resetting a service A, an error appeared stating service B was overdue by over 12k. Concerns about causing ECU damage led to stopping use.
Cons
- − Exit button returns to main screen instead of going back
- − Authentication check on every start
- − Incorrect Mercedes data readings
- − Service reset causes overdue error

Fast, reliable scan tool for independent shops
This scan tool covers most vehicles that come into an independent repair shop without the cost of tool-truck brands. It quickly identifies misfiring cylinders using power-balance data and bidirectional tests, and its topology map helps trace communication faults across modules. AutoAuth works smoothly, live data is easy to graph, and the wireless connection is reliable. It supports many resets, relearns, adaptations, and active tests across domestic, Asian, and European vehicles. Initial updates take time and the menu system has a learning curve, but overall it offers strong value and saves time on jobs.

- + reliable wireless connection
- + easy live data graphing
- + many resets and active tests
- + broad vehicle coverage
- + good value for independent shops
