Which Is the Better Value?
If you value a larger documented service-function set and newer-vehicle gateway/protocol features, ArtiDiag800 BT 2 has the stronger case. If a clearly documented update term and simpler verified scope matter more, AD900 Lite is easier to evaluate.
Bottom Line
At nearly the same current price, choose by the functions you will actually use and confirm those functions for your exact vehicle. Do not choose from the model number alone.
