You are aware that these barely work. They do not last ( bearings fail and the ventilator falls off the roof and injures people.). Also they are not good ventilators and perform very badly. The workmanship is rubbish. Don't waste your time or money.
@@MrSatukali they are not supposed to. They have a fifteen year warranty according to most manufacturers. Still, you buy cheap you get cheap performance. By the way I don't hang around all day with a camera waiting to take a photo of a cheap ventilator falling off a roof.
