I ordered this humidifier and received it late last week. It is operating in our bedroom and helping to moisten otherwise dry air that is common in the wintertime. It is an attractive compact unit, capable of handling a small bedroom (I have the 1.7 liter). It is easy to refill and runs very quietly. While I chose a size too small for our master bedroom, I am considering the purchase of the larger model, and may move this unit to our guest bedroom.
                    (I underestimated the size of the master bedroom—the description of the unit was very clear about capacity!)
