This is the second salt lamp I have purchased after finding that they help relieve eczema symptoms. This one was a bit smaller than my other one, but a fraction of the price and works just as well as the other. It emits a nice warm and relaxing light and helps improve air quality. I can feel the difference in the air when I get close to it. The switch is great and makes it super easy to dim the light to reach the desired brightness you want, so you can even sleep with it on, without it being too bright.
