Pros

Broad diagnostic and service functions can serve buyers who need more than basic OBD-II code reading.
A 7-inch screen provides a larger working display for menus and live-data viewing than a basic code reader.

The wired connection means this is not presented as a wireless diagnostic setup.

What to know before buying

Listing details to confirm

The listing is inconsistent about hardware and identity: it calls this MK808S but also compares it with MX900, MK900BT and other models, while the 4GB hardware claim is not supported by the provided model-detail fields. Treat compatibility, active-test and service-function counts as listing claims, not guaranteed coverage, confirm the exact vehicle and function before buying. Firmware updating is recommended in the listing for broader coverage.
