Just finished home renovation and some of the fans were installed by me. This is the first time having a mixed bag of brand due to the area size. Used to only Panasonic and KDK but now also have Alpha and Deka. The quality of these Alpha and Deka is just miles below Panasonic and KDK. From the structure, electronics, piping, wires, nuts and screws (a lot of kecik miao bolts and nuts), packaging and even the manual. If I have the choice, I would just stay away from them. Price is also not that far from Panasonic and KDK.
