After multiple use of different room fragrances in different variations (from bottles fragrance with wooden sticks on interval sprayer to classic oil-oil burners) I am now came across this perfect solution that beats all other variants from the field. Combining essential fragrance oil with steam ensures pleasant odors and simultaneously acts against to dry room air. Unlike some other system you will not "kill" because the smell will spread much more evenly and unobtrusive by nebulization. The lamp gives a cozy and dim light in changing colors. Who does not like the color change, either turn off the lights in whole or each choose a color that just suits him best. The use of light is very simple - you fill using the supplied measuring cup just a staggered with fragrance oil quantity of water, power cord, flick, finished. We recommend the essential oils of the manufacturer. I have tried one (Magnolia) and I am pleasantly surprised by the light, floral fragrance. But I have also added the water in the measuring cup before alternatively with a few sprays of my favorite eau de perfume, which has also worked very well. Practically on the system that the lamp after using up the water (approximately 3 hours) turns off by itself. Strong buy recommendation.
