Given that we are now past 2025, here’s a candid assessment:

| Pros | Cons | |----------------------------------------|-----------------------------------------------| | Works on 95% of 2000-2019 vehicles | No support for 2023+ CAN FD or new ECUs | | One-time cost (clone + software) | Requires Windows 11 tweaks that might break | | No subscription | No cloud updates, no online coding | | Great for Ford/Volvo/Mazda/JLR | Outclassed by newer tools like OBDLink or ThinkDiag |
