Very nice tool for cellphone or tablet car diagnostics. You download an app that takes care of control and display functions and is auto updating. There are a few things to consider though. There is no support for Chrysler, Dodge, Jeer, Ram, Fiat, no Stellantis vehicles. There is also a 4 vehicle limit. Both are to reduce cost for licensing Stellantis support and due to unlimited vehicle lookup. If these caveats do not present an issue for you I highly recommend it due to it's enhanced functionality and ability to connect via Bluetooth. Over all a great buy for a nice tool.
