We found the design of the device great and very appealing. The device also managed the cooling capacity for a room with approx. 18sqm without any problems, but at 30°C outside temperature it takes about 2-3 hours to get to 23°C in the room. Low temperatures did not make it.
However, the device is very noisy. In the bedroom only with level "low" to use. But then you hear strange hissing irregular noises. Possibly also vibrations from the grid inside the device, which are triggered by the compressor. The compressor itself is not so disturbing as it is a uniform deep noise. However, the interlude or vibrating is irregular and this irritates quite nicely. Not to use in the bedroom for us. Unfortunately, this does not seem to be an isolated case with our device, because also an exchange device showed this behavior and also acquaintances with the same device reported about it. In the end, this was also the knockout criterion for this device. Not usable for us.
Lack of smart home support also contributes to the fact that the overall price/performance ratio is not right for us.
