Bests & Worsts Reviews from Amazon

I live in a medium sized 1 bedroom apartment. I wanted a small fan. I originally bought a smaller, $40 Vornado fan and found that I had to turn it all the way up to circulate air in the room, which meant the fan made a lot of noise. I did some comparison research on the Vornado web site, and found that this fan (the 660 series) has the lowest "power consumed to air moved" ratio of any other Vornado fan, meaning this is the most energy efficient fan that Vornado makes, so I returned the small fan and traded up for this fan. This fan is much larger than what I thought I needed (and twice the price of the $40 fan I was looking at). This fan has better air circulation on the lowest setting than the smaller fan did on the highest setting. Since I'm using a lower fan setting, this fan is very quiet. Plus I have the option of turning it up all the way if I really want to move some air. The directional focus of the fan works as advertised. I put the fan in one corner of the room, and can literally feel a column of air at the opposite corner of the room. The circulation of the fan works as advertised. I can feel the fan drawing air in from the sides when I stand to one side of the fan. When I first turned the fan on, it was on a high shelf, and it drew up dust bunnies from the floor and spat them out. The temperature in the room feels more balanced. The AC doesn't seem to run as often (I'm writing this in the middle of the July 2010 heat wave in DC). There are no hot spots or cool spots in the room. I feel cooler, having a constant, subtle flow of air around me. I'm very happy with this fan. This is one product that works as advertised and so far it has been worth every penny. I move it between the living room and the bedroom every day, and I will likely buy another one of these fans soon.
