Gotcha, good to know. Mine is upside down if you couldn't tell from the video clip. I'll keep an eye on it. Thanks for the info. Worse case I buy another mount and Lil Blizzard and do a normal pole mount in 2 corners. Still will come out as the same price as the AC 9", but better circulation.I don't hang them upside down, it was just hanging there after the clip broke. He replaced them with the updated version. The new ones are thicker plastic and the screws go through on an angle instead of straight like the old ones. They feel stronger then the old ones
