Has anyone installed a ceiling fan with bi-directional rotation function?

Any feedback on its effectiveness in this climate and whether it is worth paying the premium to get one?

Another question, has anyone bought ceiling fans off Taobao or AliE? They sure have some very nice designs and reviews but a bit apprehensive.

When it comes to ceiling fans it is mostly a case of your budget and preferences towards the design.

AC vs DC? Pros of the DC is it is less noisy, more power efficient and usually less resistance. The cons are the pricing which is usually more expensive than an AC motor one and that translates to both purchasing and repairs, the other con is it is more sensitive to power surges and a bit more sensitive.

KDK vs Panasonic? Panasonic owns KDK and their major components are identical. My KDK remote in the living room can also operate a Panasonic fan at the dining area.

Most recently I needed 2 smaller sized fans, I bought a Rubine Ampio and an Alpha Vannus Pico. I am very satisfied with both and cheaper than buying an equivalent KDK or Panasonic.

Both fans are DC.

Both are left to run on reverse full speed 24/7 and been so for 2 weeks now. I have no complaints on it and it is still very silent and very stable despite being installed by someone that never installed a fan before this.

The only thing I do not care that much for is the light on the Alpha is not the best as the colour temperature makes it look as if the bulb is on its way out.

If I were to buy it again I would definitely buy another Alpha as it is value for money at only rm329 with 5 years warranty.

3 vs 5 blade? No such thing as 3 better than 5 or 5 better than 3 as there is no such thing as a fan with 3 or 5 blade where everything about it is 100% identical. Even that KDK fan where the design looks identical minus that one is 3 and the other is 5 has some differences with the blade pitch and some brands the motor is more powerful but it does not have as high a rpm where it is a 5 blade. Like I said previously it will be on the basis of taste and preferences.

There are 2 reasons for this.

The first reason is when used with an open window it will remove the hot air from the ceiling area thus minimising the load on the air conditioner.

The second reason is where it is used in a room with air conditioning the cool air will blow from the 4 corners of the room rather than downwards, this helps a lot in keeping the room cool, minus the dry air often associated with air conditioned rooms and finally it also helps to better stratify the cool air around the room.
