I have been using the levoit classic 300s smart ultrasonic smart humidifier for a couple of weeks.  I really love it. Ni love that you just have to take the top off to fill it.  I love that you can set it on auto, low, or high.  There is a night light with 2 settings, a button to black out the humidity percentage it shows, the settings button for actual, low or high, and the power button. All of these are in the front for easy access.  I don't use the black out button, because I forgot it was on and didn't turn it off before I left. I just put a small piece off paper over the humidity percentage. The instruction manual was very easy to follow.  I'm very very happy with my humidifier.
