Thank you for your input but I was asking on the air flow; KDK is equally unreliable these days and not going to pay a premium for DC motor fan by Panasonic / KDK

I am surprised this thread is still alive after so many complaints of Deka fan products.  The conclusion is:

1. Deka distributor in malaysia dun care shit about customers complaint. they never responded to any threads here.
2. Dun try to make your deka fan go faster by changing the cap. Look at all the fan blades fell off pic in the earlier posting.
3. Low quality product with high price tag. stick to the reputable brand.

I regret buying my windless wonder of a Bayoo 4 from Pana. Do you want to take it off my hands at 30% off? it is hardly used, I think in its lifetime only used less than 3 weeks worth of runtime.
