LIRUGUO Electric Compressed Air Duster - 51000RPM Super Powerful 3-Speed Blower with 6000mAh Fast Charging, Replaces Canned Air for Computer Cleaning, Keyboard Dusting & Car Detailing | Perfect for Electronics Maintenance, Office Cleaning & Automotive Care

I had a bit of a hard time getting this to work as you actually have to hold down the power button for quite a little while to get it going and for some reason that didn't seemed to work for me. Once you get it going it has 3 levels of power and it is quite strong for a such little duster. This will save a lot of money on the long run since you don't need to buy those compressed air cans that are not good for the environment. Their customer service is wonderful too, going above and beyond to make sure you're happy with your purchase.I bought this for cleaning my pc and I am so happy I did. First of all, no more cold hands from canned air! Its relatively quiet and the air flow is really nice on each of the 3 speeds. Cleaned my whole pc on one charge and shes still going strong. Easily 30 min + of use on 1 charge. 100% recommendThe best feature is the 3 blower speeds. They hooked me as soon as I tried it out.Extremely strong for a cheap and small duster. Would recommend to everyone! A lot better than the disposable canned dusters.I was amazed at the power this has. 3 speeds with attachments and a light in the handleStopped working after one month very expensive for one month item very disappointedI got this in hopes of replacing the compressed air cans I've always used to keep dust off of my computer components. The air compressor is powerful and it comes with a number of attachments. I used it to reinflate an exercise ball and it worked great. I tried it on my computer in place of the aerosol compressed air and for now I have to give it an 'incomplete'. I used the 'pressurized air' attachment for this task and it removed the dust that had accumulated since my last cleaning. Everything is clean now so I don't have any dust to continue my tests. I'm not sure that any of the attachments focus the air as tightly as the little straw on the aerosol compressed air cans. My hunch at this point is that it won't be able to replace aerosol compressed air but will make it necessary to purchase it less frequently.It's pretty noisy--like a small vacuum cleaner--but since it needs to generate the power to make it effective that's probably inevitable. I'm sure it can be effective for other use cases. I'm going to use it for a week or two and update this review if I have any revelations. It definitely does what it says it does--I'm just not sure if it can *completely* replace aerosol compressed air. My other minor gripe is that there's nothing provided to store the attachments. Even a small bag would be nice and I probably have something around I can adapt to the purpose. The box (pictured) isn't really functional for storage.UPDATE: I did some more computer cleaning today, opening my case and cleaning out all the dust. There wasn't much dust, but this device did a good job getting what there was. I don't think that it could *completely* replace the aerosol compressed air cans. Maybe none of the devices of this type can but for the time being I'll continue my quest to find one that can.This is a neat air blower. It works for a a lot of tasks but the size of the nozzle and overall lack of air speed is a bit limiting. It can't blast the way cans do, but it is way more efficient for less intensive applications. Overall, I feel this device is hampered by the lack of a small diameter nozzle attachment for more intense dusting, but is fine for less intensive uses.
