Bought this feeling sceptical. Our bedroom had black mould and condensation & we woke every day to even the surface of the bed feeling damp. I got itchy feet, runny nose/eyes and was cold all the time. Since buying this dehumidifier, it has surprisingly been working a treat. I even used it to dry out wet paint in the bathroom quicker. My only fault with it is the water tank at the back. It doesnt always sit how it should and you have to give it a light whack to ensure its properly in the right position. Otherwise the red light on top will say the tank is full. Not too noisy, but we only use it during the day. Leave it on middle setting for it to run periodically throughout the day. It also seems to cool the room - so i will be testing that this summer! All in all a very neat, tidy appliance which is perfectly big enough for a 25m2 bedroom, hallway and bathroom. It pretty much does most of my huge flat.
