Forscan.
I got the AE first because that is what all the cool kids were using at the time.
The first problem came when they "upgraded it" by turning it into a complete headache to use,
removing important features like saving your vehicle information.
The update flashed the firmware on the needlessly proprietary obd connector
so there is no rolling back to the good version, and It would constantly freeze when trying to log.
Then the thing stopped working completely.
They had me send it in for repair and that was the last I saw it. Tracking showed they got it, but it never arrived.
AE customer service is awful, the product is awful. I'd rather make wild guesses and fire the
parts cannon at a problem than give them another cent.
Thankfully we have forscan and if something happens to the obd connector I'm not over a barrel to replace it.
