Good humidifier, a few negative features

I needed a large capacity humidifier, and the essential oil diffuser was an added bonus. Pros: This product worked as advertised, and produces a nice thick stream of mist that does not leave a residue or white film. Runs about 9-10 hours on max with a full tank. Since it's a large volume of water, it requires a lot more oil to get the scent in the room. I started with 6-8 drops, but eventually was up to 14-16 or so. The motor is very quiet, and the auto-shut off worked as expected. Cons: The blue light on the dial is fairly bright and there's no way to turn it off. Turns red when it's out of water, but still just as bright. In order to fill the water tank, you have to lift it off the base and usually spills a bit of water. I'm sure with practice I'd get better, but a top-fill unit may be better. Lastly, although the vaporizer motor is almost silent, there is an audible gurgle and bubbly sound periodically as the water moves from the tank to the humidifier. It's a spring loaded cap, and was noticeable while trying to fall asleep. I'm going to return the unit, but only because of the light and the water tank. Works great as a humidifier but I need a dark, quiet room to sleep.
