I bought two and one of them didn't charge, but they replaced it without any problem. It is entirely made of plastic and has the full RGB spectrum in very vibrant colors, and the light diffuses as it should for such a small lamp. It has 3 settings for the white light, where you can have it separately on, you can choose the RGB shade you want for the main body of the lamp, and have only that as light or both the white light from the mushroom at the same time. It also has a mode that turns on for 10-15 minutes and then turns off by itself.
