It's 110 degrees in the shade and there's no relief in sight. At only about 9 inches wide, the 540B creates a hurricane like effect to vent an area of stale, stagnant air. It's due to the patented Vortex action indicative of Vornado's grill design. It's more than for mere appearance. It twirls the air that passes through with up to 65 feet displacement.

This is an excellent fan. No other brand I've encountered moves so much air. I have owned two other Vornados for several years (the 530 model) and wanted something similar, but with clip-on capabilities. Since I was using it for evaporative cooling on a reef aquarium it also had to be made of corrosion resistant plastic. The 540-B fit the bill. This fan - like other Vornados - is not for the faint of heart. It's powerful, moves a massive amount of air and as such could not be described as quiet. The clip is unbelievably strong and the construction of the entire unit is of superior quality. It's the same size as the 530 model but has 2 instead of 3 speeds. If you are looking for a relatively small fan that moves a lot of air and can be clipped on to just about anything, then the Vornado 530-B is the fan for you.

This "Air Circulator" is in a league of its own. It is extremely powerful. I am very pleased. My only concern is with the durability of the clamp. It doesn't seem to be as well made as the rest of the air circulator. But for the last 30 days, it has been just fine.

I clipped this fan to my treadmill and it works great. The clip is strong and the fan hasn't moved at all. The fan also is strong and keeps me cool during my workout. I highly recommend it.

Popped this fan on my treadmill and it works wonders. Clamp is nice and tight and sturdy. I can get up to 10 mph which is pretty stressful with lots of vibration and the fans hold tight. This is it on "high". Can get noisy, but on a treadmill while running no concern. It isn't noisy enough to drown out music or tv on treadmill. The "low" setting is nice and quiet, great while walking.

The "high" is a brisk breeze enough to keep me cool at those speeds. The "low" perfect for walking or cool-down.

Enjoy!!!

I'm posting this on all Vornado listings on Amazon, as all potential purchasers need to be aware of the shortcomings of Vornado's warranty policy.

I purchased two fans from Vornado direct. Both were larger, more expensive units (280 & 285) that had either ten year or lifetime warranties.

One year after the purchase, the 285 began to vibrate upon start-up. The fan blades would barely revolve, and the fan emitted a loud rattling sound.

I called Vornado's Customer Service and spoke to a Paula. Upon describing the problem, she stated the motor was bad and e-mailed an RMA. However, she told me I would be required to pay for the return shipping.

As this was a large, heavy, floor standing unit, I told her that I would be returning the motor only. She gave no indication that was a problem.

The motor was delivered to Vornado. 5 days later, they called and refused to perform the service without the remainder of the fan assembly. They also had the temerity to tell me that I had voided the warranty by removing the motor, and wanted to charge me for the repair, but again, only AFTER I spent additional money to send the rest of the frame back!

I have 3 problems with Vornado's actions in this matter: 1.) I had to return a defective IN WARRANTY product at my expense 2.) I told Paula upfront I would only be sending back the motor, and she didn't object, and 3.) where was I supposed to get a box large enough for a plus-three-foot-tall, floor-standing unit?

Disgusted, I told Vornado to throw the motor away and forget the whole thing. When I disassembled the unit to extract the motor, I found the fan to be of a cheap design and construction, so it would be possible that I would have a similar re-occurrence of the same problem in the future. Why waste further money on something that might fail again?

BTW: Both phone calls involved LONG hold times to get a customer service person. So, if you're forced to call them regarding service, be prepared to have something else to do while you wait.

Vornado might claim to stand behind their customers. After dropping the original +$150 on the two fans, going out-of-pocket for the shipping to return the motor, and having to dispose of the useless, motorless 285 frame, I can definitely attest to having felt Vornado there. My advice: Find another fan from a better company. Vornado brags about how their products are built in the U.S.; who cares, if you're not going to support your customers?
