I like the idea of it but in practicality it is loud and not all that sturdy, despite it's looks. By "sturdy" I mean that when you try to press any of the buttons you need to hold the unit with your other hand because it will move. That's a problem when you are trying to operate one handed in a lying position from your bed. I find the output of mist and the scent fine but the motor is loud which I couldn't tell in store when I purchased. The light is too bright and the only options are light on or off. The buttons have no illumination and are impossible to see, I need to get up close and shine a light on them in order to see what to press. For the price I would expect the ability to customise run times (set the west tank to start at 7:30 PM and stop at 10:30, etc). I just feel it was not worth the money and I'm sorry I didn't read the reviews here first.
