It is of great ease of use. I had never handled, and I do not have to consult the user manual (except for checking the number of drops of essential oils that I could join).
Simply fill the tank (6l maximum) of water, like coffee. Then if we want to drops of essential oil (40 drops regime ylang ylang for me) on the sponge that fits in a drawer under the tank.
It is recommended for better efficiency to place the humidifier in the middle of room, but given its aesthetic still a little clumsy (despite their best efforts, it looks like a big kettle or coffee) and the short length of electrical cable, j ' I preferred to put it on one side, along the plintes, away from the most fragile furniture.
Once the cable is connected, the humidifier starts immediately started. Be careful to adjust the flow (like a vacuum cleaner with a wheel) and choose steam or ultrasound, orienting the direction of steam if necessary, otherwise it can be quickly héberlué by heavy vapors released!
Another advantage that I discovered about humidifiers is that they donent also feel that the best parts are heated, which is perfect for a chilly like me.
However, this device does not just miracles: besides its size, it requires careful maintenance with maintenance every 3 days (inherent to its function!). It also makes noise (little, but if there is sensitive it can ruin the nights) and I have not found a way to operate the device without the bluish light, certainly the most beautiful modern effect but giving the 'like sleeping with a big night nearby. So I put it in the room while I read / surfs the Internet and then moved into the living room at bedtime.
In short, a solid unit, guaranteed for several years, which meets the basic needs.
