The operation of the device is intuitive through the highly visible symbols.
The level indicator seems to work is not always correct, I had 20 degrees in one room, but the fan has shown yet 23 degrees.
The fan rattles over medium - high setting strong, making it noisy.
The breeze mode is a nice change to be constant blows.
The light of the level indicator is very garish blue and can interfere in the dark, if you are very sensitive to glare.
