Negatives:
sometimes difficult to screw bolts and are relatively quickly around. So use suitable screwdriver and push enough. But it has enough spare.
Floor stand magnet too weak; stay tuned to the housing and hardly dissolve during movements too easy. But is also great without feet, in which case, of course, no air can come from below.
For me personally, could quiet a few more front ports to be there, but it wants / needs just not any.
