Wow, single fan is as good as the dual fan configuration. It has everything I need to set it up and get it running. It's quite, has a speed control and includes a power source. For the price, quality and included accessories I highly recommend it.

Works and doesn't break the bank. I needed it to build a cooler for a solid state mini PC. Particularly liked the adjustable speeds.

Works as described. In use for a few months with no issues. Only Draws 1 watt of power as per kilowatt meter.

This is a great little fan! It's very quite, has 3 speed settings and it can either connect into a USB port or a regular outlet with a USB adapter. I use it to cool down my large Harman-Kardon stereo receiver. It sits flat on top of the receiver and makes no noise what so ever with the added rubber stick on feet! My previous HK receiver use to shut off when it got hot...not with this one!

I used this fan to provide some circulation for a orchid I have in a enclosed plastic box. It works good but there is one issue that cropped up. The average humidity in the enclosure is 75 to 80 percent all the time. The top of the 4 nuts that hold the gard over the fan blades have slighty rusted in the extremely humid enviorment. This has not seem to affect the function of the fan which has continuously worked for 5 months as of this review. Does make a winy noise, not dead quiet, but not enof to bother me but the fan is in an enclosure which dampens the noise. If I had any complaint I would have liked the electric cord longer. Its roughly 40", with the speed adjustment swich about half way. The plug-in is usb so I had to use an adapter to plug in to an extension cord. Works fine and I have never had the adapter get warm. A good little fan for the price.

ESTAVA RECEOSO E DESCONFIADO AO COMPRAR. MAS CHEGOU E TESTEI, ME SURPREENDEU. ESSE PRODUTO É MUITO BOM, POSSUI 3 VELOCIDADES QUE PODEM SER ÚTEIS EM VÁRIAS APLICAÇÕES. APROVADO.

Es exclente trae 3 velocidades que si lonutilizas como extra en una consola o pc disipa el calor muy bien t se mantiene muy refrigerado el objeto, solo que si subes la maxima velocidad se nota mucho el ruido si estas en un lugar tranquilo

Perfect for what I needed - making a small, desktop air cooler - I didn't want to have to sauder wires together so USB powered was exactly what I needed. Small enough to fit in the palm of my hand, quiet, and the three speed switch is very handy. I will buy again if I make another air cooler.

This really is a great product. Especially for the price. It’s a breeze compared to my old setup. Before I came across this gem, I’d been using just a regular old computer fan that I’d yanked from Dianne’s computer and an old camcorder battery I kept from my days working on adult films. It didn’t have any fancy settings or any of this newfangled protection they put into everything nowadays. It was either on or off and if I grabbed it while it was running, I nicked my fingers and that’s just how it was, until I found this product. It’s a little bigger than my old fan, so it fits snuggly into my back pocket, with plenty of cord to reach my new power bank I keep in my other pocket or my satchel, and it keeps the air moving. The HML switch is small enough to fit through my belt loops and with some planning, the cable can easily be strung through my belt loops keeping the switch conveniently placed at my side for easy access. Stringing it through my belt loops also keeps excess cord from being snagged by my flailing arms or those damn doorknobs Dianne insisted we get when we remodeled our home last year.I couldn’t believe how great the HML controller is for quick and easy control of the fan speed. The different speeds are great for a variety of cases. The lowest speed is great for just keeping the air flowing and keeping my pants cool and dry while the highest setting is great for quickly dispersing increasingly pungent smells. And it’s so quiet. Even on the highest setting, the fan remains silent. No more awkward “what’s that humming noise?” questions from people I got with my old fan. If it weren’t for the constant cool breeze, I’d forget it was even there.The grates on both sides are a MUST-HAVE. I thought I would just take them off, but they really do provide great protection on both sides of the fan. I no longer nick my fingers when I remove the fan from my pocket when I forget to turn it off. I haven’t had to put a new bandaid on my finger in days. And no more awkward fidgeting trying to readjust the fan in the heat of the moment after it’s become snagged on the pocket lining. My old fan constantly got caught up on my pocket lining. But the grate keeps the lining away from the fan blades no matter what. And the grate is strudy, too. Only the one time have I managed to depress it far enough that it came into contact with the fan. But, that was only because I accidentally sat down on the metal bleachers at Mathew’s baseball game with it still running in my pocket. But, even then, the grate bounced right back and didn’t bend at all. It’s still as straight as a rabbit’s ear on the Fourth of July. I’d recommend this product to anyone looking for a pocket fan. I like it so much, I’ve already purchased one for work, one to keep in my pickup, one to keep in Dianne’s car, and even one for David because I know he’ll just love it. There’s nothing better than having a cool crevasse in the heat of summer, being able to disperse those wrank bouts of gas after Dianne’s world famous enchiladas, and warm apple pie. Just the other day, Dianne and I were grocery shopping. I let one slip in the produce section down there at the Walmarts. I flipped the switch to high and in a matter of seconds, it was a row over. The poor girl stacking the carrots started gagging because she thought some of her produce had gone bad. But no one looked at me for a change.

I bought this to cool down an AT&T NVG599 modem and router combo that I noticed would get very hot with incredibly slow wifi, requiring a daily reset. I looked inside the router and saw that there was no active cooling at all, only two heat sinks with no airflow. Putting a fan in front of the router seemed to fix the wifi lag, but the only fan I had was big, loud, and probably used too much electricity to cool a single router. Due to the terrible internal design of the NVG599 modem I had to set the fan to high, but the fan is very quiet even on high when placed in my living room. However, It might produce a humming that would be noticeable in a small and quiet bedroom.It's totally irresponsible that companies design wifi routers without active cooling because hot routers are a real issue that leads to slow wifi, but I can see why ISPs would be motivated to cut this particular corner. Whenever I've asked technicians from AT&T and Verizon that have come to my house to service my internet they found this idea to be ridiculous and blamed it on my cheap internet plan. But from my own experimentation, I know that router heat is the real issue because Ethernet connections work fine and wifi is still slow even when testing the speeds right next to my router. Before you shell out more money for subpar internet from the big ISPs, give this fan a try.
