I have been trying to find an oil diffuser for several months and have purchased and returned so many! This Pure Himalayan salt diffuser is exactly what I was looking for! Set up took just a few minutes. 2 power buttons (one for the mist and one for the light) which are "soft touch" (no need to apply any real pressure to get them to work). The diffusing mist starts as soon as you turn it on (no "warm up" time). I LOVE the beautiful glow of the salt lamp!  On the lowest setting, its not at all obtrusive when trying to sleep. On the highest setting, its perfect for a night light! The "mist" that comes out is very light (nearly impossible to get a photo of it) but lasts for several hours and the scent of the essential oil added fills our livingroom with light wonderful, not over powering aroma. If you are looking for something to humidify the air, I do not recommend this, but if you are specifically looking for an oil diffuser and or salt lamp, I 100% recommend this!!
