Overall I am very impressed with this. I like the sleek design. The size is nice and holds a lot without the need to refill each night. The opening at the top is nice and large which makes refilling a breeze. I like the double mist opening feature which allows you to disperse the mist or direct a larger mist all in one direction. We have utilized both options already. I do wish these would be manufactured where the tops could be completely removed for piece of mind sanitizing. I had envisioned this to be really easy to clean and disinfect, but in actuality its very similar to all other humidifiers we have owned so far. I never feel that they get as clean as they should without a good scrub. The larger opening does allow my hand to get further into the tank for scrubbing, but a full lift off top would be ideal.
