My mother had bought this and we still have real first used nearly 20 minutes to get it at all in transition. The problem is that you can not just connect it to the power of the diffuser, filling with water, and off you go. You have to disassemble it first, since the description is inside the diffuser and that exactly where she grew up, the water comes out. The disassembly is nowhere described and is only possible with "brute force". If you have done it then, helping a description and not because it is in English. So you going to instinct. When you have filled the water, you have to press both buttons at the rear of necessarily, pressing just one, it lights up only as a lamp, only when you press and the second button, the diffuser kicks off. On the front side there are two indicator lights, one red and one blue, they are permanently lit during operation, what we perceive as really disturbing. If he's up and running, it works well and also very quiet but due to the difficult handling and the annoying warning lights, I can not recommend this diffuser.
