This little air blower / vacuume is great. It blows air at acceptable pressure. The size of this blower is also great. It doesn’t take much space. The battery life seems to be good. The vaccume power doesn’t seem to be very strong but it is acceptable.

Build quality is great. The slider design allows you to adjust the air speed to your exact needs.
Great for electronics and coffee grinders. Not quite powerful enough to blow out the pooled water from the crevices after a car wash. The battery life is definitely lacking on full power, will run you less than 4-5 minutes.
The other thing I have not been able to figure out is the vacuum and filter attachment. Instructions don’t show you how to use it.
In comparing it to my Wolfbox blower, this doesn’t come close in runtime or the force of the air. Although both units claim 150K RPM, the WolfBox will literally blow this one away while lasting much longer. This K&F blower is much lighter though and its step-less slider makes it worth buying.

I like this thing! It screams like a banshee but seems to be a pretty powerful duster for its size, and it looks well made and sleek.

The device has a USB-C charging port on the bottom and a battery indicator on the side. It also comes with various attachments of different sizes, including a brush that can really get into the nooks and crannies of your PC, keyboard, etc.

The duster has a vacuum mode as well, which is cool (I dusted my keyboard and then vacuumed the errant particles off my desk). The vacuum doesn’t seem to be crazy powerful, but it will work well for its intended purpose (as well as to remove crumbs and the like).

Overall, I would say that on its own this duster is fine for dry particles; if the dust doesn’t easily come off when you run a finger over it, it probably won’t blow away either (then again, if you’re in that situation, you might have bigger problems to worry about).

For a battery powered air duster, this packs an incredible amount of power. So much so, that turning up the pressure, you can feel the force. You feel your hands being pushed back. It deals with dust very well. Ideal for pc cleaning. The air duster is nicely shaped and is compact.

Button controls the power and also to switch between vacuum and air duster. Long press turns on or off. Pressing the button 3 times switches between air duster and vacuum. Vacuum isn’t very power to be fair. But is sufficient for duster.

The instructions is ok. It isn’t laid out well. The English is over two rows. Not in a logical way either. Doesn’t show how to attached the attachments. There’s one, the vacuum sleeve, not quite sure how that fits. Also doesn’t explain how to switch between vacuum and air duster.

Has a fair amount of attachments. Which should cover most of your needs. Plus 3 additional filters and a bag. It is a rechargeable battery via USB type C.

This is a small but mighty air duster. It comes smartly boxed with a selection of nozzles, a storage bag, a USB-C charging cable, five microfibre cloths, spare filters for the vacuum cleaner dust chamber, and instructions. The unit is rechargeable using the supplied USB-C cable, charge level is shown on four white LEDs. The duster fits comfortably in the hand and is very easy to use. The unit features an on-off switch and a variable power slider; on full blow there is a noticeable “recoil” when holding the unit. There are different nozzles that can be fitted for different tasks. The air duster doesn’t have a useful front spotlight, which is a pity, it is, however, relatively quiet in operation. The air duster can be changed from a blower to a vacuum cleaner function by pressing the on-off switch three times, the power level LEDs then flash. The dust chamber can be fitted to the front of the unit and nozzles attached to that. It works reasonably well. An air duster isn’t something I thought I needed until I had one, now it gets used for lots of tasks, blowing out dust from radiators, cleaning filters in air purifiers, and blowing out the dust canister of bagless vacuum cleaners. This is a powerful unit, it’s well made, and genuinely useful.

Have tried cheaper options here on Amazon but they were crap. Not enough pressure despite a larger size. This one is great. Blows hard (in the good way). You get what you pay for. Spend a little bit more money, this is totally worth it.

I set my expectations somewhat low with this, as numbers like '150000RPM' and '54m/s' had me thinking the performance claims were exaggerated nonsense.

However I've been absolutely blown away (HaHa) by the performance of this. You have to readjust your expectations from things like hairdryers and heat guns; this is a completely different beast. It's like a jet engine in your hand. You can actually feel the thrust it's producing as you ramp up the power output. No wonder they use these kinds of motors in EDF RC planes.

Something I also didn't anticipate was a reasonable feeling of quality across the whole kit. The main unit has a gorgeous visual design, a pleasing finish and colours, minimalistic branding and markings. It has a reassuring weight. There is a metal mesh with a hexagonal pattern over the intake and you can see the metal blades of the turbine motor through it. It doesn't look cheap in any way.

Basically whoever designed this cared about the fine details and absolutely nailed it.

Even without the narrowing attachments it makes light work of blowing away surface dust. The noise output is actually much lower than I expected; high-pitched but not at all annoying or piercing as I'd assumed.

The tactile power button must be pressed to power on (and three times to switch to suction/reverse mode), so it's not easy to accidentally enable the motor. Once powered, a smooth sliding switch controls power fairly precisely. Overall a very well-considered design and very satisfying to interact with.

The claimed USB type-c charging speed is 10W. I found it to draw 7W with a ~60% full battery, so that sounds reasonable. Given the form-factor I don't doubt that it's using 18650 cells as claimed. I haven't tested run-times, but this is not the sort of device you're going to be using for hours on end.

The provided accessories are generous and (while mostly just plastic funnels) have the same decent quality as the main unit. The soft pouch is a welcome addition; as are the (embossed!) microfibre cloths.

Given the attractive box, pleasing visual design and provided accessories, it's pretty clear this was intended to be (and would make) a fantastic gift for someone.

I would have preferred it not to have a rubberised surface, as they always perish over time; similarly I'd like the 18650 cells to be accessible and replaceable to extend the lifetime of the device; but these are relatively minor complaints.

This has become one of my new favourite things.

Great tool for cleaning your PC and peripherals. Great pressure for blowing out the dust. The suction for the vacuum is decent as well. Comes with attachments and a bag to hold everything.

good product, cheap and pretty

Don't hesitate to buy it, got it on sale, and have saved SO much money blowing out my PCs.
