Review: Simple and ideal for automation with a smart plug. - Simple mechanical dial to control power and oscillation. It was ideal to plug into a smart socket. It's quiet on the low settings so good for bedrooms. Adequately powerful on the highest setting but louder.
Review: Cools air well, build quality is quite poor! - The function of the fan is great, however the build quality is quite poor! Cooling effect: Given 4 stars because the fan does actually cool the air down whereas most fans just move the hot air around. Build quality: The round foot is 2 pieces that should clip together, but don’t and the top part with the dials on is loose and moves around while trying to turn it on.

### ⭐⭐⭐⭐⭐ Simple and ideal for automation with a smart plug.
*by P***H on 17 September 2025*

Simple mechanical dial to control power and oscillation. It was ideal to plug into a smart socket. It's quiet on the low settings so good for bedrooms. Adequately powerful on the highest setting but louder.

### ⭐⭐⭐⭐ Cools air well, build quality is quite poor!
*by B***N on 12 July 2025*

The function of the fan is great, however the build quality is quite poor! Cooling effect: Given 4 stars because the fan does actually cool the air down whereas most fans just move the hot air around. Build quality: The round foot is 2 pieces that should clip together, but don’t and the top part with the dials on is loose and moves around while trying to turn it on.

### ⭐⭐⭐⭐⭐ Nice compromise between a fan and an air con
*by D***L on 28 June 2020*

Very useful appliance when the heat strikes. It is sufficient for getting a cooled down feel. It is not as cold as an air con but a lot more efficient than a fan, based on my experience. You can also add more cooling effect to this system by inserting a frozen block into the water tank included in the packaging. The remote control is a pleasant addition to it. For this price I cannot say a word of complaint. On top of that, there is a heating feature. It kicks off straighaway when it get cold in the room at a swing of a button. It is really a good gadget. For my part, I am happy about this. To those who are moderate not demanding too much, I can recommend this 4-in-1 appliance.
