OBD diagnosis

Hello together. I would like to buy an OBD diagnostic device. After hours of searching in the www and comparing, I came across Autel MaxiSys Mini MS 905. (https://www.premiumparts24.com/autel-maxisys-mini-ms905.html) Now my questions: -someone has already had experience with this device and can tell me about it (diagnosis depth, whether it is partly possible to encode, whether you can do a placement test with it, etc.) -someone knows what the updates cost when the first year I also came across Autel MaxiDAS DS708 (http://www.wgsoft.de/…/168-autel-maxidas-ds708-deutsch.html) -Can anyone tell me what is the difference in functions between the two devices? What do you think of Autel devices? Of course, I don’t know that it’s a comparison with an original manufacturer’s test device. I’m mainly concerned with reading fault memory from different manufacturers, sometimes some vehicle values. (Lambdawert, ABS speed sensor or airbag resistance) to query, perform actuator test or reset various adaptations. (I know this is already very much required) I hope someone can give me information.
