This is my 2nd unit -- not because the 1st one (4 years old) is broken (it's still going strong, with a LOT of mostly low and medium speed use every Summer), but to have another for a different location in the house. I love the smooth and quiet sound (not as quiet at max speed), durability, made-in-USA, energy efficiency, and speed adjustability.
The main floor of our home has a circular layout of rooms. We have some window a/c units upstairs, so a fair amount of cool air wafts down the staircase to the main floor. We use 1 or 2 (depending on how hot it is) Vornado fans on the main floor to circulate that cooler air around the entire floor...and to provide a mild (or stronger) breeze in every room of the main floor.
