    This review is about a variation of the product

    It connected to the car and the phone immediately. It recommends the MAXOBD app, the only problem with which is that it doesn’t work with Android Auto.

    This review is about a variation of the product

    Very easy to use, it connected immediately to the phone (Android), the app (MAXOBD) has a nice interface, which the manufacturer recommends.
    Very convenient is the ON/OFF button on the device, without needing to remove it every time.

    It really works, it pulls the codes from the errors, it doesn't just tell you it's the lambda sensor, in Greek or in English it gives you the code, you type it into Gemini and it tells you what it is, it connects easily with Bluetooth and with Wi‑Fi, I haven't tried the data to be honest, I give it 5 stars because it also has other data, engine RPM, temperature, etc., and it is reliable and economical, there are cheaper ones too but I preferred a branded one with good reviews

    I bought it to see the avance and the L sensor for fuel quality
    in case you have an android screen you can see from the car's screen and not have the phone in your hand

    This review is about a variation of the product

    Although it works with the Torque Pro app on the phone like many cheaper ones, it does not work with the Multiecuscan app on the computer...

    Not supporting iPhone even it says it does. There is one video on YouTube( using another app) which supposed to help with the connection to your device you will receive an error “Not connected to ECU!” . Very disappointed.

    Quite fair for its price. It detects the fault and you can see if it is serious or not... I managed to turn off the "fault" light on the dashboard for a minor issue.
