For the price, very good, functional, and quality.
It definitely does not reach the RPMs it claims.
There are other much more powerful and more expensive ones.
With these, whatever you get is a risk.
You can see in some of them that the photos show two and three different models.

Mediocre fan speed. Good if you want to blow your keyboard clean of dust and bread crumbs. Not strong enough to dry your car or blow leaves out of your driveway.

Very powerful machine that has made things much easier for me. I mainly use it for cleaning computers and the interior of my car, however I believe it is suitable for many other uses as well.

I wanted something to be able to clean my computer, I was looking at some compressed air sprays and luckily my eye caught this particular little gadget. It blows the computer just fine, cleans it from dust (not the ones that are stuck due to humidity), the keyboard, the dust from the car dashboard, it works great, it blows like a strong hairdryer, so it will also be great for lighting a fire by blowing on the coals.

Its battery doesn't last long, at full power it lasts a few minutes, 5-10 at most, it doesn't charge quickly, the box says it charges in 4 hours. It's for quick little jobs like the ones I mentioned before, to do something thoroughly and quickly and not to take your time!

For 10€, it's quite worth it, personally for me because it's a better solution than buying compressed air sprays which are consumable!

It discharges very quickly even without using it, but it does its job. I would prefer it to be a bit more accurate, for example to have a small screen to show what mode it's in or its battery level, because it only has three lights that are either all on when it's full or all on when it's empty

Very powerful and effective. I deduct 1 star because it starts a bit oddly and the battery drains quickly when you use it on turbo.

I would like it to be a bit stronger. It is for a quick cleaning of the computer. It does not remove dust that is stuck due to moisture.

It does the job but the battery doesn't last long and to get it started I have to dance a sirtaki with the on/off switch until it decides to work

it's not worth it... nothing like the description... those in the photos cost 60-70 euros.. this is good just to blow something but very weak in no way is it what it describes. of course, I will return it to give the same amount to get a better one..

Very good and convenient. It is not going to do the job that a large blower does, but for cleaning computers, which I use it for, it is very good and the main thing is easily portable. It also has a good battery life.

We expected it to be stronger, and it is definitely not quiet. It sounds like a vacuum cleaner or a regular leaf blower.

A year later I changed my review to one star. I had bought the expensive model for 100 euros. The battery doesn't last even 10 seconds after hours of charging. The last blue light keeps flashing, indicating that the battery is still charging. I have left it all day to see what will happen. Nothing. I'm crying over my money.
