Excellent humidifier. We bought it during the dry winter months. I like this humidifier as it holds a lot of water. It also has an adjustment knob that allows you to change the power. The light inside emits a warming glow. The light can also be switched off by itself. The humidifier is disassembled into three parts. This makes it easier to refill the container. The only downside to this humidifier is that the bottom sometimes gets filled with excess water, making the humidifier inoperable. My simple remedy is to just drain the water and put the container back in place. I don't think this is a big problem so I gave it 5 stars instead of 4 anyway.
