This device works great, he fucked humidity 10 to 20% dan home within hours. It is also perfect for drying clothes quickly.
Its 5L tank gives a good battery life before being filled, which is perfect.
Its only flaw is its noise and vibration generating (a upstairs, put on the floor in the middle of a room it vibrates the walls). I take it one star for this defect which causes we can not run it at night as way too noisy.
