What! I would have never thought something so small could be so powerful! This thing makes you feel/sounds like you're in a wind tunnel. Very happy!

I’ve been using this K&F Concept 2-in-1 magnetic air duster for a couple of weeks now, and it’s already paid for itself in saved compressed air cans. The power on this thing is no joke — even on the middle speed setting, it blasts dust out of my keyboard crevices, PC case, and camera gear with way more force than I expected.
What I didn’t anticipate was how much I’d use the vacuum function. It’s not for deep carpet cleaning or anything, but for sucking up crumbs around the desk, dust off shelves, or stray bits from small repairs, it’s been surprisingly handy. Switching between blowing and vacuuming is quick, and the magnetic attachments make swapping nozzles painless.
Battery life has been solid; I’ve run it through several clean-ups on a single charge, and it hasn’t lost steam mid-job. Plus, no more having to deal with cold hands from traditional air cans. For anyone who’s into electronics, photography, or just wants to keep their workspace tidy without disposable air cans piling up, this is a must-have tool.

Holy crap this thing is powerful! It's got crazy air flow for the size of it. You can get a lot of functionality from a device so small and versatile, especially if you make use of the several attachments. Also came with a number of brushes to keep it clean and a spare filter, I'm impressed!

It moves a substantial amount of air, enough to lift up the nozzle end of the device if you point it downwards, and almost stand itself up.
The vacuum is a bit underwhelming, but that's not really its primary feature.
Seems to dust well, puts out similar feeling air as an air compressor does, just wish it also came with a more focused nozzle, rather than all the brushes.

From recommendations to delivery, the product itself is top-of-the-line for its size, perfectly constructed and assembled.

I wasn't expecting such power! This blower/vacuum has truly amazed me: it's lightweight, practical, and above all, much more powerful than I imagined. I've been using it for small household jobs, and it's proven invaluable for cleaning windows, screens, radiators, and other hard-to-reach areas.
The force of the airflow is impressive, removing dust and dirt in a flash.
So far, I'm very happy with the purchase—we'll see how it holds up over time, but so far, it's far exceeded my expectations!

Over time, a PC case becomes a real dust trap. The fans draw in fresh air (along with the dust), and it settles on all the components, fan blades, cables, etc. There's one solution to avoid: using a vacuum cleaner. You risk sucking up components...
Alternatively, you can blow it out. There are cans of compressed air for this purpose. But it gets expensive.
When I saw that Amazon was offering this electric dust collector, I didn't hesitate.
And I have no regrets:
The pros:
✔️ Very powerful.
✔️ The power is adjustable. And thankfully so, because too much power can damage components. With another device of this type, I unknowingly disconnected one of my hard drives!
✔️ Comes with a multitude of accessories.
✔️ Battery operated. ✔️ Good battery life.
Cons:
❌ I can't think of any.
It comes with all the necessary accessories: nozzles, brushes, etc.
I recommend using the lowest power setting and gradually increasing it as needed. When using it on a PC, be careful around the most delicate components. I read somewhere that it's best to block the fans with your finger, as the airflow will make them spin. Not necessarily in the right direction, and certainly not at their usual speed. I imagine that wouldn't be good for them.
I also used it to dust places inaccessible to a vacuum cleaner.
For the keyboard, blowing isn't enough. The narrow nozzle allows you to get into a few places, but most of the dust is just moved INTO the keyboard. For a proper cleaning, disassembly is necessary. (Take a picture beforehand, so you can put the keys back in place!)
Tip: Wear a mask, because the air coming out of the PC is very dusty! :)
In short, a good product, which I recommend.
