Set realistic expectations
3/5
I'm torn with this machine. At the higher settings I don't think it is any quieter or more effective than a traditional bladed fan. However, at low settings it is quieter. A few days ago, when we were suffering very warm nights, while it didn't cool the room, when set low, to blow cool air directly across the bed, it did enable us to get some sleep we otherwise wouldn't have had.
My advice is to moderate your expectations of what you think this fan can do and you may well be satisfied.
