It was the first USB device I got to try a 5V 1A power adapter but the charger gets hot so I don't use it at night. I prefer one with a plug. The ref.no:147-29071 is the white one (72 black color).

Very weak and poorly designed.
Because it does not direct the airflow strictly straight, after 20-25 cm it has no effect. For mini USB fans, choose one that has foils in front of the fan to direct the airflow straight, much more efficiently. It's impressive how big of a difference they make.

For office use and to keep you cool with a gentle breeze, without poking or stabbing you, it is very decent. Quiet. 100% value for money

I have two. Metal construction, on-off switch, one-meter USB cable, rubber pads on the metal base, adjustable up and down, quiet, efficient. I’ve forgotten to turn them off several times, and even by the next day they were still working without overheating or any other issue. If you want one that also moves from side to side, the Singer DF15 USB, which is slightly larger, is absolutely fantastic! https://www.skroutz.gr/s/29959468/Singer-DF15-Anemistiraki-USB-4W-Asimi.html

Very good little fan for its price. Now if someone thinks that with 10 euros they will get a fan that will blow as much as the north wind in its prime, they have understood something wrong...

I bought it because I had a similar one that looked like it would blow as strong, believing that it would blow just as strongly. But this specific one runs on USB power and maybe that's why it's not as effective.

For a desk fan that will give you a light breeze when your colleagues don't want the air-conditioning too strong, it's just what you need.

It is quiet and really refreshing, the only negative is that the cable loses contact and stops, I hope it will hold and not stop working.

A good and economical solution if you are looking for something small and practical. The air it produces is noticeable at a maximum of 1-2 meters and it won't make you feel cold. I wanted something simple from a fan of this size and budget, just to give me a slight breeze so that I don't sweat, especially at night or when I'm sitting at my desk working. It guarantees that, so it suits me. The construction seems decent so far. As for the sound, at a distance of two meters, the intensity measured at 35-37 decibels (compared to an air conditioner in relaxed mode at the same distance, which measured at 37-40 decibels. I mention this comparison for someone to understand the sound). I think it's a very good choice for its price.

It lasted one summer, the production quality is a bit lacking in such devices. No matter how good the value for money may seem, it is better to spend a little more for something more reliable

Awesome for the one week it lasted!
At a distance of one meter, it does the job but unfortunately after a week of use, it said goodbye to us.

Excellent for the office during the summer months, when we all disagree about the ideal room temperature.

Good metal construction, doesn't consume much energy, blows quite well (not full power, but just right for a distance of 50 centimeters, you know), and finally, it doesn't make much noise. With headphones and music, it's not heard.

Edit: The fan suddenly burned out. It was good while it lasted

The fan is very nice, although after about a year, the fan moves from its position (I don't know what's happening) and it ends up somewhere else. It makes a loud noise and I have to hit it a little for it to work again, although after a while it goes back to the same issue and eventually I turn it off. I don't know what's happening or if anyone else has the same issue as me. Maybe it's worth buying depending on luck and if nothing happens to it. Of course, its usage must be good because sometimes it falls (probably that's where it broke). From what other comments say, it doesn't have such good quality and I agree because it really seems so. I believe due to its quality (and based on the other comments), it's not worth buying and it's better to go for a better and more quality brand.

Excellent for the job it was purchased for.
I deducted one star because out of the two identical ones I bought, one is stronger than the other, which means it is a little bit unreliable.

Very good fan, small and functional.
With a 10000mAh power bank, it lasts several hours of use.
Sleeping with it blowing from a distance becomes very pleasant.

It works perfectly! I had a previous imitation of the model that made a terrible noise and moved around my office while it was running. This one is quiet and stationary. It's worth its money.

Fair product. It makes very little noise and cools locally at a relative close distance

The best thing for a free vacation. You attach a powerbank and have 400 hours of fan for sleep

Very convenient and small desk fan VFM that helped me a lot last summer while I was working and it was very hot. It's not very powerful, but at a distance of 1.5 meters, you can feel a difference. It makes almost no noise and the good thing is that it connects easily with a simple USB to a computer or a hub, so it doesn't occupy a whole power outlet.

I have it in my office connected to a mini dock. During the summer when I was boiling, I would put it on top of me and it helped a lot. Yes, it is small, obviously it will not cool an entire person and you don't feel it from a distance.
But for what I wanted it for (to cool me locally, to be discreet for the office, and not needing a power outlet), it's perfect.

Excellent for the money it asks.
Quiet, sturdy construction. I have bought 3 pieces so far

Amazing purchase!! I used it all summer for my office at work and it saved me!! I highly recommend it!!

Truly the best, unbelievably quiet and small enough to fit in my desk drawer and provide me with a breeze. Perfect

For the job I bought it for, it cools down my phone and me during gaming perfectly fine, especially for its price!

Very good for the first month of use. Silent and I have it running continuously for at least 7 hours! I think one size up with a slightly larger diameter is the perfect choice for someone who wants such a product.

For its price, it is an excellent choice. Suitable for office use. In terms of noise, it is comparable to a PC fan, meaning it is noticeable in quietness but I would say not bothersome, especially if playing music covers it. Another plus is that it has an ON/OFF switch at the back, so it can stay plugged in continuously without having to plug and unplug it.

It is small and relatively quiet, I took a photo next to the AC remote for scale. It does its job just fine, for a dollar it's okay.

I bought this specific little fan for office use. It is excellent despite its size. I have placed it at a distance of 1.5 meters and it is just what I need. It doesn't rotate on its own, but you adjust it yourself, you give it the angle you want, it doesn't have steps for higher or lower performance. You connect it to your computer with a USB port or if you want to take it somewhere with you, you simply connect it to a power bank. The sound doesn't exceed the sound of the computer's cooler. That is, it's below 20db.
The fan is made of aluminum internally, if I'm not mistaken, as well as its frame, which is definitely not plastic.
Yes, it's worth 100% of its money.

UPDATE!! It's a beast!! Now I use it even during sleep. I have it at a distance of 3 meters and it does its job perfectly.

The product is great for the office, with the logic that you will have it at a distance of 0.5-1 meter from your face. It doesn't need more air because it dries the eyes. Its noise is minimal and in any case tolerable. Based on the price, it's great.
