The availability of over 60 service reset functions, including ECU coding and bi-directional support, provides comprehensive diagnostic capabilities, from engine and transmission to brake and airbag systems. The scanner's user interface runs on an Android operating system, potentially offering a user-friendly experience; however, some users might find navigating such an advanced tool challenging if they are not accustomed to using Android devices.

Connectivity is enhanced with support for CANFD and DOIP, facilitating quick data transmission, although users must ensure these protocols are compatible with their vehicles. LAUNCH offers frequent updates, which are crucial for staying current with the latest vehicle models and diagnostic needs, but users should verify how long these updates remain free. This scanner is best suited for professional mechanics or workshops needing high-level diagnostic tools for a diverse vehicle range.
