well - there is unfortunately also a BUT

the stick is quickly and easily installed - however, the "German description" only partially available - even if the language setting in GERMAN, help videos are all in English !!! And that just does not work !!! We are in Germany un then one must also have a "German Bedineungsanleitung" expect and indeed completely in German and not only partially. Who then does not understand English or can read, is a little duped, then you have either of someone who can be helped or fumble through somehow and that can not be so the inventor for the purposes.
Once you durchgewurschtelt, everything is pretty easy / easy!
Some films are blurred, and this certainly is due to the APP and not the stick !!!
It is great that you simply stop a unit or part and eventually may continue to see precisely at the point where you stopped, without having to look - awesome !!
Would say - this is the future!
