The diffuser is well made and easy to use. I love the colors of the lights and if I used it in a room other than a bedroom I would have them on all the time. For the bedroom at night the lights are very bright so I keep them off. The top is plastic and there is a ceramic type smaller cover underneath that you take off to put the liquid and oil into. My only complaint is that water builds up (which is like any diffuser you'll buy) and since the top tapers all the condensation will run out of the hole of you set it down on the countertop which you have to since there are two parts to open. However I feel that this is a small issue I just work around since it is a nice diffuser.
I think this is a wonderful product, it is quiet, easy to clean out, and just as easy to set up again for the next use. I am very happy with this purchase, and I recommend it to anyone looking to buy one.
I have 3 diffusers , and this one has quickly become my favorite...it is adorable and so relaxing with the lights changing color
The Simply Earth diffuser is great! The quality is very nice. I have another diffuser where the plastic is cheaper and it is not as well made. This one has thick plastic, the essential oils don't tend to gunk up and leave any residue that I can see, and it's a pleasure to look at with the varying light colors! I keep it on my desk and it does fill my small office nicely. There is a timer for 2hrs, 4hrs, and an "on" feature that I've found lasts about 5 - 5hrs.
