I'm aware that as always with buying cheap crap like this it may well stop working after a little while, but it's a risk I'm willing to take at the price. My main concern is having something connected to my OBD port where it could theoretically change stuff on my car and/or track all my driving data. How much can actually be done via OBD on a car as old as mine (2010 NC MX-5)?
