Mainstays 2.2 L Ultrasonic Humidifier is rated 3.1 out of 5 by 9.
Rated 5 out of 5 by from Cool mist! Just bought this cool mist humidifier to see how well it worked and it is great! Easy to fill and lasts all night. It is also very quiet! The dial allows for as much or as little mist as preferred. I love it and will buy a few more for around the house

Rated 5 out of 5 by from Best little humidifier I bought this little humidifer a wk ago & I do not regret it. I have bought & returned the high end humidifiers & returned them because of one thing or another. This one does everything it says it does & more. Easy to clean (5 min) before refilling again lot of steam, u control it. Am going to go out & buy another for my other bedrm.

Rated 3 out of 5 by from Its ok but small capacity I bought this last month for my kids room and overall its nice and does the job although the water tank gets empty before the kids wake up in the morning.

Rated 5 out of 5 by from Great cool humidifier I bought the unit during this snow storm time in December. It is very efficient and quite. One tank of water lasts for 3 nights if you turn it to 70% mist capacity. It cost little electricity about 22 watt. Other machine use up to 400 watt. Very happy with it's performance.

Rated 1 out of 5 by from Not Impressed Bought this item about 2 months....Within a month switch started not working all the time, then just 3 days it just wouldn't turn on, water managed to drip into electrically compartment and fired the guts of it.....Won't Work at all now

Rated 1 out of 5 by from Not great Well it worked for about 2 weeks. Then nothing. The light went from green to red. And water began to seep through the motor's grill on the bottom of the item. That's not normal. The water jug doesn't come off easily and I always had to remove the jug over a sink unless I wanted to get myself and my bedroom floor wet. Small water capacity.
