I think kdk fans are good.

But a fan is not a technological wonder.....
It's a simple appliance that many companies can  can make.

Main issues are no longer motor problems are these are mass produced to a level of near perfection. Usually it is just discrete components like capacitor or fuse.

You can get a cheap fan. Turn it on everyday while on warranty to weed out the weak components. If there is it usually happen during this period.

After that the fan will last for very very long. 

There are 2 types of fans:

1. Sheath motor 
2. Ball bearing motor.

The sheath motor wears off faster you can use around 5yrs then the parts wear off and you have noise.

The ball bearing fan lasts upwards of 10yrs as ball bearings reduce the wear and tear. Some of the companies offer 6yrs warranty for ball bearing fans. If you want a fan that lasts 10yrs buy this type of fan. Cost is $100+

A cheap fan $20 is good enough and does last....giving value for money.

Those who insist on buying branded ones like KDK and Panasonic...by all means you can pay more for assurance. I just think it is unnecessary.

You are lucky, never encounter white smoke out coming from the fan while you are sleeping. Branded fan, why expensive is mainly due to quality material used.
The durability is guaranteed.
