Received on time. Easy instructions, and easy to set up. Poured water to level line, added essential oil in small glass reservoir and plugged in. Works like a charm. I bought the blue/white color combo and love it. The LED lights work great and add a nice feel. 7 different color combo's to choose to go with décor. Both high and low mist works well. Low mist shoots 3"-6"out top, high setting will produce mist about 8"-12" or so. Visually the mist is not very dense or thick, so if you are looking for a diffuser that mists a strong or foggy type mist you can visually see from across the room, this may not be for you. Personally the mist is medium on a scale of 1 to 10 in terms of a thick or thin mist, which works for me. If you had a really strong mist, you might have more issues with moisture building up on surface. So far, I have not had problems with moisture pooling up under unit, even on high setting running for several hours at a time. I live in a 650sq/ft apartment, and with diffuser on high sitting in my living room, kitchen, bed/bathroom my entire apartment smells well scented in 20/30 minutes. Strength of scent is determined by amount of oil added to small glass oil reservoir. I like the 500ml size. It is not too big of a diffuser, but large enough that I am not constantly adding water/oil all the time. I run this for most of the day, and only have to fill up in mornings. Anything smaller and I would have to refill several times a day. Noise level is quiet, very quiet. Overall great product. Curious to see how long this lasts.
