I ordered this system because it is currently the only mobile split system with inverter is - ie with infinitely variable cooling capacity. When unpacking the poor workmanship of the case fell to negative. Cheap plastic, irregular gap dimensions and a very scratch-sensitive and sometimes uneven surface. Well ... it was supposed to be a style of furniture but with air conditioning. Although the system cooled very well what may be due to the technical data and expected yes, but made a very unpleasant operating noise. A mixture of low frequency hum (the plant was vibrating so strongly that the vibrations on the ground were broadcasting) and an unpleasant high-frequency buzzing noise similar to the sound that makes a flash when charging. I was of the opinion that this can not be so normal, I complained at Amazon and it was immediately sent a replacement unit. Although the replacement device made other noises ... but did not cool! I suspected that the coolant was missing. This was confirmed then, for not only the refrigerant was probably escaped during transport, but also the oil from the compressor. This had in fact spread during the short test and the subsequent displacement of the device on our parquet flooring and leave ugly marks that can no longer be wiped away.
