The negatives: unit (fan) was filthy, already unpacking came to meet the black-brown dust, remote dirty disgusting brown - something going, even in B-goods, not at all. The device is the size of a VCR.
When the unit is hot after about an hour, the Levee Breaks away although the looped signal no problems over the antenna cable to the TV. Device is sent back and would prefer to order by another manufacturer and marketer something.
