After unpacking, I was a bit confused because I did not expect that the diffuser is made of plastic. Product photos and quite lush Price were believed me that it is glass housing. Nevertheless, the diffuser does what it was built. Water with added fragrance oil is atomized and spread the fragrance throughout the room. It is operated via touch-buttons which react well. In the LED lamp can be between the three RGB colors (red, green, blue) to select or activate gentle color change. The device turns off automatically when the set timer expires or no liquid is present. Without filling the device does not turn well. I also find it a bit of a shame that the lamp LED separately can not switch (why?). Without water - no diffuser without diffuser - no spa light.
