I think Alpha Cosa is a good choice. I did consider Alpha Cosa too last time. But because I malas, I would prefer 3 blades than 5 blades for easier cleaning chores. 2 extra blades per fan, that would be 12 extra blades to clean

I can't really compare with KDK or Panasonic since none of my family bought those brand recently. The "latest" KDK I have seen to compare is in my parents house in my hometown which is almost 15 years old.

But then, I my current house, I installed two brands, Alpha (Alkova Dezi) and Aeratron (AE3+ & FR). So, I can compare those two.

After 6 months of usage, I would say, so far I am satisfied with the purchase, especially since I decided to spend extra solely because of aesthetic. In terms of blade built quality, I would say the quality of Aeratron is hit & miss. The blade for my FR was good, but then, for AE3+, the quality of the seem of the blade (where they combine the top and bottom part of the blade) was poor. It is not visible if you see from far, but it is visible when you climb and see up close. I reported the "defect" to NSB and they came with one to one replacement, but still, there isn't much improvement with the replacement blade. I don't have such problem with FR though, or even my cheaper Alpha Alkova.

In terms of performance, the air movement is pretty good, but the significant edge over normal fan is it's quietness. You could barely here the sound of the moving air compare to normal fan, even at top speed. Unlike my Alpha where I could hear the "whoosh, whoosh" sound of the moving blade/air. Other than it's quietness (and of course the looks), there isn't nothing much to shout about.

In terms of service, I would say, it is above average. All my reported problems were immediately attended by their SC & technician (the "defect" and some installation mistake by my contractor). The downside is, I don't think they keep any spare parts, so, all replacement parts are taken from their new in box unit and if the unit is not in stock, you'd have to wait for the new stock to arrive.

And if you plan to buy Aeratron, I would suggest you call their technician to install. They would charge you RM55 per installation, slightly expensive, but better be safe since you're installing a 1k++ fan. Don't repeat my mistake as I let my contractor install the fan, and they screw up the installation. Lucky for me, NSB rectify the mistake FOC (I reported that my fan was making abnormal sound, turned out my contractor missed one part).

If I have money, I would install all Aeratron in my bedrooms as well. But then, I don't, so I installed Alpha instead.

I think the price difference between AE3+ and FR isn't much. I bought two different model because AE3+ didn't have 43" that time and FR didn't have 60". Performance wise, I can't really say since it is two different sizes in two different areas. One in the living hall and one in the kitchen. But then, both are quiet compare to other fans. The remote control on the AE3+ is slightly better than FR since it comes with digital display, so you know the current speed and direction of your fan. For FR, the remote control comes with only up and down button for speed, so you could only guess the speed based on your experience with the fan.

Low ceiling, go for aeratron la boss.

If you don't mind the look of the wall fan, why not.

I’m using Alpha Alkova Dezi. So far so good. Wind noise is slightly noticeable compare to my Aeratron, but still better than regulator fan.

Alpha Motto looks nice. Not sure about the performance though.

I could vouch this as well. My house is using Aeratron AE3+ and FR, and Alpha Alkova Dezi. Aeratron is so quite, making me feel that my Alkova Dezi is so noisy, despite it is actually quieter than other common fans

For Aeratron better call NSB themselves to install. If I'm not mistaken they only charge about RM35 per fan for installation. Don't let random installer cincai install your expensive fan.
