Very small, silent, it reads without problems all my videos without jerkiness or bug. It's actually very stable and works as well as ethernet wifi. You just plug it provide ethernet to play videos as blu ray (it stutters a little wireless).
Finally, the jukebox mode with the display of Jacquettes is really very good. You just spend a little time to properly rename the files. Some are very well done tutorial online.
Note that I recommend to master English: no documentation in French (except Quick Start Guide).
