Recommended for colds

The product name: "facial sauna" irritated a little, because I had been looking for an inhaler with water evaporation that roughly works on the principle of a boiler bronchitis.
In the cold device very little tap water is poured into an aluminum insert with a small measuring cup, simmer or boil to evaporate the water that brings on the temperature setting. With me only the supplied "facial sauna paper" is used. Here can be set via specially tailored, circular pulp inserts a convenient evaporation of example, peppermint oil reach. I have also given two drops of oil on a piece of household or 4-ply toilet paper, which is attached to an evaporator top and closed with a Deckelchen. The inhalation time is at setting: limited "Hi" in about 15 minutes, after which water must be added in order not to let the appliance dry go. Comfortable is the time delay with automatic shutdown. The accessory materials are all made of plastic, but durable. A minor steam and inhalation regulation is possible by turning the respective missions with adjustment of Locheinlässe.
Why the use of the equipment is estimated at a maximum of three times a week seems to me a mystery. I use it as part of a cold or simply to relax and take a deep breath almost daily.
How good it is with the durability, I can not say because I have acquired it until about a month ago.
I would buy the unit definitely go back, even if I want a larger water reservoir and an improved steam regulation.
