I agree thats why I never send them because you wont hear back,all you can do is hope...I use to send them when I owned the ds708 but never ever heard a peep...but I will say they listen to the forum so you will get better feedback from here than data logging.

 I suggest to send an email. 

 Recently, we have close focus on datalog, could you please tell us the S/N of your tool that has uploaded datalog? Thank you!

In my opinion if the log data were been followed up properly this tool can be one of the best after market tool as the users of the tool are the one to make it improve...............But, when users are sanding log data files and if the Autel Engineers don't follow them up its no point in sanding them......Also I would advice the Support Team when they receive the log data file the sander should get a confirmation email with the reference number to prove that the log data file was reached to the server...............like other tool company do...................
