The mini-stick I bought, and HD movies to better stream on Pi. In addition I have exchanged the Micro-Stick against this. The change was no problem. Old out, new in, goes. Of course, the Mini is slightly larger, has it but also a WPS button, which I have not yet tested. At my FB 3272 I get approximately 120mbit / s displayed between approximately 4 meters and a wall.
I am happy. Just as I had imagined. Both the size, shape, processing, Plug'n'Play everything works fine and there is no reason to deny a star.
