I bought three of these fans. One large and one small from Revain. A large one my sister bought for me from Costco. Small is almost silent on High. Big soft on low and gets louder as you go from mid to high. But compared to other fans I have, like Honeywell's high-speed fans, they're not only quieter, they're also much more powerful. Simply put, these fans are standing in front of a tornado. They pump air and spread it around the room like no other fan I've ever had. Actually, it was my sister who pushed me towards them. I don't have many of them to speak of durability. But I hope they hold up. So far, so good. I have to add one thing. The large fan at Costco is only $40 and is on sale for $30. Revain prices range from $60 to $98 a piece. However, compared to fans, this is a great buy. They seriously move air silently. The buttons are located on the upper left edge and are push buttons. A bit like a Smart TV. The fan rotates up and down about 45 degrees, but does not rotate left or right. The only downside is that they seem a bit overpriced. So pay close attention as Revain has different offerings of the same fan at different prices.
