I’m not as qualified as you, but have been working on my own cars my entire adult life. I have the BAFX dongle and torque, and also the bluedriver. For what it’s worth, I completely agree with everything you said about those.

I have the BAFX one, and it is ok, but then I bought the blue driver and it gives me so much more. It gives me all sorts of vehicle specific codes that the other one didn’t give me. I have the app, and I think I had to sign up for it, but I’m not paying any subscription. And I honestly don’t even remember if I had to sign up for the app or just download it.
