Works well but…

Once you get it to connect everything works fine, but sometimes getting it to connect to your phone is problematic. I do not know if it is a problem with the unit or just the app. Either way it is annoying.

Paid app but then you pay again in app

Yeah first you pay it to download then buy enhanced pack if you want to see all the sensors. I mean I downloaded car scanner and it have more features as a free app. I can’t see my atf temperature in fusion but in car scanner I can. So I unlocked the lifetime option in car scanner rather paying this developer. Sorry I paid for half the features and this should be highlighted first not later. Not asking for refund, you can keep it.
