Fast Delivery. Optically very anspechend and well finished. Bit fiddly is the insertion of the collecting container after emptying. The unit is very quiet. Comparable to the noise level of a refrigerator. Works as from the company Trotec describe. The power consumption is at 2 hours full load at about 1 kWh. But not yet a final statement to the accuracy adjustable humidistat. Display at 60%, compared device shows 58% humidity. After 4 inserts the device for jeweis ca 4h I'm very happy with it. I do not have it 5 stars because I do not know how the seller (Fa. Trotec) for warranty / complaints behaves.
