Autel is a good scanner but they have made it very complicated. You have to waste a lot of time and nerves to change the language, and even if your dealer answers you after a week like mine, then you are wasting both money and time,I bought Activation for my MaxiCheck MX808, I reset it, and after the update I don't have a single car in the system, I turned to everywhere and no one helped me, and I plan to change the Autel company
