Nice fan for desk area
344111
Just picked this up locally for my computer work area.  Nice mounting options with the desktop stand or clip (which I am using) and took under 1 minute to assemble.  Fan is quiet and certainly powerful enough if used in close proximity even on the low setting.  Easily adjustable and appears well made also.  For the $11 price I paid I find it hard to beleive I will not get my moneys worth here.

Much quieter than most fans I have had in the past.  It sits on my desk next to my phone and callers aren't disturbed by it.  Airflow is not as much as I would like it to be, but this is probably the trade off for a quieter sound.  I'm pleased with the item.

Nice fan - pushes air around nicely. The fan is located in a small to medium sized room, and really is a rather quiet in comparison to others. Easy to assemble, and quick to set up. Nice features to this fan - Overall feeling it was a good purchase.

I bought this fan for my desk at work and it is perfect.  It is small and takes up very little space on my desk.  It is very quiet and the noise that comes from it is not distracting at all.  It keeps the air circulating and if I want to feel "cooler", I just move it closer to me.  I highly recommend this for someone who needs a desk fan in a small space.

High quality fan for my desk!

I previously bought a cheaper plastic usb desk fan a few years ago and it finally needed to be replaced. When I ordered the Opolar 6 - I didn't pay attention to the size. It's larger than the cheaper plastic fan I had - but still fits nicely on my desk at work. It's a good looking fan.

This little fan works great.  Just what I needed for my desk, which is in an airless part of the house. The low setting sets up a nice little breeze that's perfect for me. It looks great, too.

I needed a fan with a nice and gentle breeze for my cubicle at the office and this fan fit the bill. The fan is very quiet and in fact I have a hard time hearing it. One of the benefits of this fan is I how I can easily clean it. Without the fan cage catching dust and blocking access to cleaning the blades, cleaning this fan is a snap. The retrostat dial to adjust the speed works well, but don't expect this fan to push like 10" fan. With the adjustable neck I can angle the fan to blow a perfect breeze and it holds the position without any vibration or creep. The fan is built solidly and everything is put together well, in fact the base is a bit hefty which was a surprise. The USB cord is soft and flexible. Sometimes these cords are a bit stiff and unwieldy in holding it's shape, but not this one.

Because it uses a retrostat (and I haven't cracked it open to see the wiring) I would recommend that you don't over adjust the speeds to quickly. When I first got it and turned it on nothing happened. I turned the dial half way and a gentle touch got it going. Now the fan spins at the lowest setting. Just needed a slight break in from the manufacturing.

Good desk fan. Could be better. I use it at my work desk and it's a little noisy no matter which position I bend it. And it's made of plastic. Gave it 4 stars because of the noise which isn't too loud but still heard.

This little fan is quiet and much more powerful than it looks. Got it for use at my office and they are not sitting at nearly everyone's desk.

I really like this fan.  Small footprint but has plenty of airflow, and has a very consistent hum that serves well to drown out noise.  I think it would be too loud for people who don't care about background noise.  Also, it being powered off USB makes it a good work desk fan.

This is a sturdy little fan for blowing a quiet breeze.  There is only one speed but it's sufficient while sitting at a desk.

These are great as a small-footprint desk fan at work.  It doesn't move a ton of air, but it's just enough for when the AC at work isn't working as well.  These are also pretty decent for white noise for sleeping.

The fan works very well. I like that it has a stand or a clip. I wish that it had one lower setting, the lowest setting is some times a bit too much for a desk fan.

This fan has worked well so far and compliments the beautiful wooden furniture in my office.  I haven't ward any noises yet (as suggested by previous reviews).

Great little desk fan.  Quiet, good air flow and takes up little space.

I got this fan for my workplace desk because it gets really hot there. It's definitely a no-frills fan, but seems made well enough so that the plastic parts (virtually everything on it) won't break unless abused. The fan tilts down maybe 5 degrees, and tilts up about 40 degrees. The on switch is on the back, which can be annoying, but the recessed grip areas work well to turn it on with one hand (I hold it in place with my arm when reaching over the top to turn it on and off).
It's very quiet when on low, and has an acceptable level of sound when on high. I find that low is plenty of breeze for me when it sits two feet from me on my desk.

Cons:
1) it is all plastic; I don't see much durability if it is moved around much, or if the tilt mechanism is adjusted often.
2) the fan blades are unbalanced just enough that the fan portion has a slight wiggle when on, but it doesn't affect the base and I can't feel it through my desk. this may be a concern for some depending on the amount of vibration.
3) when turning it on and off, it causes my stand-alone desktop computer speakers to make a 'pop' sound. This may be due to the speakers being plugged into the same 6-outlet expansion strip, or because of something else, but I haven't had this occur with these speakers in the decade+ (yes, really) that I've owned them.

Other thoughts:
The paperclip holder area in the front of the fan is "cute", but almost too small to be useful and seems to be more of an afterthought to make the fan's design stand out as a desk fan. I would guess perhaps 10 paperclips max OR 3-5 rubber bands, but when the fan is tilted down the tray may be awkward to use.
I can't comment on running durability as I've only used it for 8-12 hours of on-time, but so far so good.

Overall, I'd recommend this fan. Very good airflow, great price, and it should last "long enough" since I take care of my stuff.

I use this fan every day in my office at home. It isn't loud and it fits right where I need it to be.
