DOROBEEN Compressed Air Duster, Cordless Handheld Air Blower, Stepless Speed, 41000RPM, Portable Rechargeable Built-in Battery, Electric Air Duster for Computer Keyboard Electronics Cleaning

Charge it before testing it out. Works fine. Could be a little more powerful but this is all I need to keep the dust from harming my PC and office devices.Amending the first review. The charge lasted for only 3 short uses of this air blower. That was less than 2 minutes of dusting out my PC and other devices. That is scary. More to come. Loss of one star for now.Amending again. Charge lasts a very long time now. I love it!

excelente producto de calidad y con bastante fuerza

Works for what I need it for. Wish it was stronger.

For the past several months, my desktop pc would reboot almost every night while in sleep mode, and sometimes while I was using the pc. And recently the drive letters of two removable USB devices would be reversed after the reboot, causing me to have to change them back to the original, which wastes time.I have an HP gaming pc, not because I'm into gaming, but because I wanted a fast desktop pc. I've never had problems with HP machines in the past, and assumed it was a Windows 11 problem.So I went online repeatedly for advice on how to change Windows settings, and on running diagnostics to correct whatever was wrong. I also updated the driver for my graphics card to the latest version. Nothing worked.Finally, I went onto a website which recommended that the first thing you should check is if there is excess dust inside your pc.Now this sounded like a solution. So I turned off my pc and shined a flashlight on the fan behind the front bezel and sure enough, the fan, which blows inwards, was covered with dust.I did research and found the Dorobeen air duster. I liked that it had an attachment with a soft brush, so that I could loosen up the dust prior to blowing it out.Next I looked at some YouTube videos on how to properly clean out the pc. The videos included such information as (1) hold onto the fans so that the duster doesn't damage the internal bearings, (2) how to remove the front bezel on my specific machine and (3) advice to take the machine outside to avoid dust getting spread around inside the house.So I did all of that and now, 8 days later, my machine has not rebooted while in sleep mode a single time. The excess dust was in fact causing the desktop to overheat, and so as a protection, the machine would automatically reboot in the middle of the night.This air duster did the job, and I look forward to keeping my desktop for a long time, now that I know how important it is to keep it free of dust! Highly recommended!

Los accesorios son muy útiles para limpiar el teclado y esas partes en las que sólo la presión del aire no puede sacar el polvo

This is amazing. It has a very powerful air flow but is gentle enough to use on delicate items. If you are into lapidary or collecting rocks you can use this to blow off dirt and dust without damaging the delicate bits. I used it on my book shelves and got dust off the tops of the books. I even used it on some antique stuffed animals and they are like new. If you have nicknacks you will only have to pick the lighter ones to dust around.

This is great for hard to clean items.

I purchased this in November 2021. I used it about once or twice a month to blow the dust out of my computer. Initially, I thought it was a GREAT tool to replace expensive "canned-air."But then I noticed the last few times I used it, the battery life was extremely shortened. I thought maybe I for got to charge it? BUT NO! Now, it won't blow more than 10 seconds after a full charge. So I got about 25 uses total over a 12 month period for $50. That's $2 per usage and now it's DEAD!A single unit of Canned will last me a whole year using it once or twice a month, and the canned air is only $4 per can! Do the math,...Since I could find no apparent way to contact "DOROBEEN" directly, I left a message / question on this review link on Amazon's site where I purchased the item. I inquired about any warranty or reparations."Sally" responded a few days later: "Please contact Dorobeen. If the product is damaged by non-artificial reasons, we will provide you with a satisfactory solution." OK! GREAT, right??? (WRONG!!!!)I THOUGHT that ?leaving the message ON THEIR SITE" was "CONTACT" but apparently NOT!I have tried for 3 days to contact "DOROBEEN" directly, but,... THERE STILL SEEMS TO BE NO WAY TO DO THAT! Their "canned" answer is still the same,... "Please contact Dorobeen. If the product is damaged by non-artificial reasons, we will provide you with a satisfactory solution."So, they offer a "satisfactory solution," BUT PROVIDE NO WAY TO ACTUALLY CONTACT THEM TO AVAIL YOURSELF OF THEIR OFFERED SOLUTION!THIS APPEARS TO BE A SCAM WITH CHEAPLY-MADE AND VERY EXPENSIVE JUNK PRODUCTS!AVIOD THIS COMPANY!IN THE LONG RUN, CANNED AIR DOES A BETTER AND CHEAPER BY FAR! $50 WORTH OF CANNED AIR WOULD LAST ME ABOUT 12 YEARS RATHER THAN 12 MONTHS!!!!Signed:VERY UNHAPPY FORMER CUSTOMER!
