Amazon.com Product Description
Combining a sleek look with powerful performance, this electronically controlled floor fan features five-paddle 20-inch blades and a Cyclone grill that helps deliver a straight stream of air. To adjust the direction of the air, simply tilt the head of the fan. The unit's user-friendly control panel includes an on/off power button; a button for selecting the speed--low, medium, or high; and a button for setting the electronic timer, which allows the fan to run for two, four, or eight hours before automatically shutting off. A full-function remote control comes included, making it easy to adjust the settings from across the room. Ideal for large spaces, the high-output air circulator can be used on its own or in addition to an air-conditioning unit to help reduce cooling costs. Other highlights include quiet operation, a convenient carrying handle, and a lightweight, portable design. The UL-listed floor fan ships fully assembled, measures 21-4/5 by 5 by 23-1/5 inches, and carries a one-year limited warranty.

Customer Reviews

Good Hardware - Bad Software
This seems to be a nice powerful fan and it would be perfect except for these issues:

- It's too damn strong, even at it's lowest setting it's too strong. They should have had 4 power settings, or just make the middle and lowest ones lower.

- THE BEEP - this fan must have been designed by a def person, every time you hit the remote it beeps SO very loudly. This is a major problem.

- Too noisy, even at it's lowest setting

- Does not pivot down - I put this thing on top of my closet but it only pivots down about 5 degrees, it would have been really nice if it pivot down at least 20-30 degrees.

Fan seems fine, except for that annoying beeping!
I bought this fan for the bedroom. I thought the remote control would be useful for controlling the fan without getting out of bed. But unless you sleep along, it won't do you much good for this purpose... Every time you press a button on the fan or the remote, the fan emits a loud beep. If I were to turn the fan on/off, or adjust the speed, the beep would probably wake up my wife (or if she used it, she would wake me up).

If you don't plan on using this fan in the bedroom, at night, it seems like it would be a good fan. It is very powerful. It seems sturdy and well built. I would certainly keep it if it wasn't for the beeping, but that's a deal breaker for me. So, it's going back.

Was able to fix the beeping...
I agree with the other reviewers that this is a great fan with a couple of annoying deficiencies, the worst being the annoying beeping sound it makes whenever you press any of the buttons on the fan or on the remote. It even emits an extra-long beep when the timer switches it off, which is exactly the opposite of perfect for sleeping!

I found that it is possible to permanently disable the beeper by cutting a wire on the circuit board. I have no way of knowing whether all of these fans are precisely identical, but you are welcome to try this at your own risk if you like.

Of course you should be sure to unplug the fan before disassembling it! The plastic fan blades don't look so dangerous to me, but there are exposed high voltage wires on the circuit board. Take note of how the parts fit together when disassembling.

There are two small screws in the back of the fan, a few inches above each hinge. Once you've unscrewed those, it's easy to unclip and remove the entire front cover of the fan. At the inside top, underneath the little pod with all the buttons and lights, you will see four screws: two larger, two smaller. Unscrew the larger pair (one on each side) to remove a bottom plastic piece and expose a green circuit board. The circuit board is held in place by four small screws, one near each corner (not quite symmetrical). After removing those screws you can unclip the top plastic piece and carefully slide the circuit board right out of its housing (note how the pieces fit), revealing all of the electronics on top.

The beeper is a round black thing with a little hole in the middle, near the upper left corner, clearly labeled "BUZZER." It looks like it's stuck on there pretty good. But there is a small upright cylindrical capacitor, clearly labeled C4, quite close to the center of the board (and not particularly close to the beeper -- go figure), whose sole purpose turns out to be to connect the microcontroller chip to the beeper. If you bend capacitor C4 back a bit, you can reach under and cut one or both of its easily bendable wire legs using small wire cutters or scissors, disconnecting it from the circuit. Make sure the remaining metal bits don't touch each other or anything else. Or you could gently bend the whole capacitor back and forth repeatedly until both wires break right off; no specialized tools needed. Keep in mind that once you have disconnected capacitor C4, there is no easy way to reconnect it and get the beeping back!

Reverse the above steps to reassemble the fan. The lights, buttons, and remote control continue to work exactly as before, but with no beeping whatsoever.

As a less destructive alternative, you could try muffling the beeper itself by covering the little hole in the middle of the beeper with electrical tape or something. I haven't tried this, but I imagine it would make the beeping a bit quieter.
