  1. I was after a bluetooth obd2 scanner for a long time but the bluedriver is the one I went for. Well worth the money and its something I just keep in my car nowadays. It works on the majority of cars and its so simple to use.

  2. For ordinary users, Bluetooth OBD scanners are more suitable. They can also do full-system diagnosis and also provide special tools like Reset BLEED, Reset TBMS, Reset TDPF, Reset Oil, Immobilizer/Keys and so on. EZcheck and EasyDiag are both good choice.

  3. Your Comparison Check-List Pros/Cons Criteria is not the same per each model…it’s all over the place like a scatter-brained blonde.

    You ought to respectfully take the time & do an APPLES TO APPLES Comparison.

    Like ECU Reprogramming versus other Models with ECU Programming for example.

    Blondes are great when you’re out drinking with the boyz & getting smashed but feckless in the real-world & not even worth keeping around sober even if they give a good BJ.

    This article is worthless.

  4. Thank you for your great information.
    I’m from Libya and I’m an industrial instrument and control engineer, I have good experience in dealing with programmable test equipment. I’m going to open workshop for cars with diagnosis tools, I want my workshop is the best and I’m still confused which is the best scan tool for me!
    My workshop will focus on Germany cars like Mercedes Benz and BMW, also modern asian car , So which the best scan tool is suitable for me, I don’t care for the price?
