KOBRA OBDII OBD2 Bluetooth?

[Lukitas]

i am not sure if this is the right section but i am looking to get a ODBII Bluetooth reader for my car. I came across the Kobra OBDII reader on amazon and they are having a 38% off and was wondering if anyone used it?

Here is the link http://amzn.to/2qzwaDV

Any inputs would be appreciated before i pull the trigger and buy it.

You are going to get a $14 OBD tool for this money, don't be too disappointed if it does not work particularly well with BMW (particularly your '97 M3).
