Purchased this humidifier in hopes it would perform better than the last two we owned. It is EXTREMELY quiet and the night light is a great feature for my kids. The one downside: it claims to work for 30 hours but this has not been the case for us. Maybe on the lowest setting and even then not sure it could last that long. "Medium" power will last one night (10 hours max) while the highest setting will only last a few hours. Feeling a bit misled. Despite this, it's still working after about one month of daily use and hasn't started making loud fan noises as the other brands we have owned have done. Recommend getting the bigger model.

Have this in my son's room and has been working great for us. The power button light, when on, is a little bright as we like his room super dark. Other than that, very happy, even bought a 2nd one for our bedroom.

This item is ok. There is no humidity level setting, just low, medium, and high so the thing runs constantly despite what the humidity is in the room. Seems cheaply made, the button you push to turn it on and to go from low-medium-high really needs to be pushed hard, and there is no indication as to when you've gone from low to medium to high, you just hope you push it hard enough. Overall not really impressed with this.

I had a smaller model of this same brand and liked it quite well, but it required twice a day filling. This larger unit lasts much longer and is essentially silent when operating.
