Sadly ... i am an unfortunate owner of 5 KDK ceiling fans of the predecessor model (A11YS).
I must say they are truly disappointing, especially when they are such a reputed brand. After 5years of usage, only 1 survived. All 4 others failed because of the electronics. 1 have since been replaced last year because it either doesnt spin, or it can only operate at speed 3. We depended on this for our dining area. While we just continue to use the 3 other faulty ones (2 just stay at speed 2 and 1 stays at speed 1, unable to respond to remote's speed control). The main cause of failure is always the electronics (speed controller).
These days, most appliances fail because of poor electronics. All those inverter circuits, smart technologies in the end are good for marketing and selling the products. It is usually these features that fail first.
It does not matter if you turn off by switch or remote control, the electronics will still fail after a few years. The first unit that failed, after about 3yrs, was usually turned off by remote. But it is in the living area and hence the usage is expectedly higher. Now we live with it default speed at 2.
For the unit that was replaced, I took the calculated risk of opting for the KDK M11SU, mainly because I want to ensure that I do not need to re-drill holes to fit a different mounting bracket. At least KDK did not change the screw hole positioning for mounting bracket between the 2 models. 1yr+ now. Still cannot say it has any improvements over the previous. But I do find it a little noisier. I have total faith in KDK fan motors, but none whatsoever in their electronics.
