On the one hand, I love the way it looks. I love the lights, the water spinning round. I love the way when you add aromatherapy oils, it fills the room with the scent and gives a real sense of air freshning taking place. I also find it interesting how dirty the water becomes after a day or so, it must take something out in its operation.
But there's the but - the thing is too noisy.
I'd say it growls away at the level of a washing machine operating in the room next door. This can get much louder if you stand it on a resonant surface that provides a boom box effect.
I still love it and I still use it but I just wish it was quieter! If it was, I'd buy one for every room of the house and probably put myself up as a local distributor.
