While the price is attractive, the technical reality of using a clone is fraught with danger.
Instead of buying a full KESS V3 Master, you can start with a "Slave" version or only purchase the specific protocols (e.g., OBD only) you need.
If the connection drops or the software glitches during a write process—common with poorly made clones—the ECU can become "bricked" (unresponsive). This often requires expensive bench recovery or a total ECU replacement.
