BRUSHLESS Motor - Compressed air Duster - 3 Gear Adjustable Keyboard Cleaner for Office Good Replacement Canned Air, Electric 90000RPM Cordless air Duster Rechargeable 7500mAh

I'm really happy with this cordless air duster. I bought one of the plug in electric ones since I was getting tired of using the air duster in cans. It's really powerful and has been more than worth it in everything that I have used it on. I use it to dry off circuit boards after washing with isopropyl alcohol, cleaning off power tools before putting away, drying certain kitchen utensils that get water trapped inside, dusting electronics and computer equipment, among many other uses. I just got tired of having to unwrap the cord and plug it in every time I wanted to use it, especially outside where I don't have any outlets. I was looking for a cordless version, but I knew they wouldn't have the power of a line voltage plug in one. I bought one off AliExpress, and was disappointed right away. It was decent, but didn't have anywhere near the power of the plug in one, and struggled at some of the things I wanted to use it for.Enter the Reesibi R3 Pro. This thing is great! Of course it doesn't have the power of a plug in one, but so far it has been able to clean, dust, and dry everything I have used it on. I haven't tried many other cordless ones so I don't have much to compare it to, but after using this, I don't think I have a need for the canned duster or the plug in one. I tried the test blowing this one on a pocket scale, and it lines up with what they show in the picture and even exceeds it. It's showing about 3oz from about 2 inches away. By comparison, the one from AliExpress puts out about 2oz (and is much louder and higher pitched), and the plugin one does about 5.3oz. They may not seem like big differences, but I could immediately tell how much more powerful the Reesibi one is vs. the one from AliExpress.I really like the fact that this uses a brushless motor. There's a reason why the RC hobby and power tool industry moved to brushless motors. More power, better efficiency, and longer life. The motor in this is definitely pulling some power. The handle part gets warm after using it for a while, but isn't uncomfortable. This is also much quieter than the other ones I've used. If using for a while, hearing protection might not be a bad idea, but I also just have sensitive ears. Overall, especially for it's current price, I totally recommend buying this if you're looking for a comparatively quiet cordless air duster with high power and good battery life!

I bought this last May, used it maybe a half dozen times, and now it won't hold a charge. It will run for 5-10 seconds then quit until it's plugged back in to charge. Waste of $80. I'll be contacting the manufacturer to see if they'll replace it, and if they do I'll update this review.[edit 1/5/23] Reesibi got back to me promptly, asking for specifics of the problem and the order number. I provided those and their response was to say they were sending me a new unit. Great customer service, right? Then a couple of days later I got a message from them that said they would refund my money and (or?) send me a new unit and asked me to make changes to my review. I think it's reasonable to ask me to update my review to include how they resolved the problem. However, 2 days later I got another message from them that was more direct - they would compensate me only after I changed my review. That rubs me the wrong way. I'm happy to update this review and raise the star rating *after* I've received a new, working unit. I will upgrade my rating of the product from 1 star to 2 based on the quick customer service I've gotten. I'll upgrade it further when I have either a refund or a working air duster.[second edit 1/5/23] Shortly after I posted the above edit the replacement arrived. Per the instructions I have it running to drain the battery before charging it up. This one is working as expected, but then so did the first one I got. It worked for a few months then quit. I'll make a point of using the replacement often, and I'm upgrading my rating since they sent me a replacement and have responded quickly to my messages asking for help.[edit 1/6/23] Updating my review to comment on the customer service I received. I had a back-and-forth with Reesibi about the defective unit. They were quick to respond each time. They have both issued a refund *and* sent a replacement. That's above and beyond. I'm changing my rating to 4 stars based on the customer service. I hope the new unit continues to work well.

EDIT: INCREASING MY RATING FOR THIS PRODUCT: Shortly after I posted my review, the seller reached out and offered an unconditional refund to my original payment method and once I confirmed, they processed the refund the same day. I am impressed they did so since I ordered the air duster nearly a year ago and the product listing does not mention any warranty. That speaks a lot about their customer service and that they are concerned about their product's reputation. Both of those are growing in scarcity on Amazon, which is largely why I didn't even consider reaching out to them first, even though their product description states to contact them if there's any problem.For this reason, I'm increasing my review to three stars. One star for the air duster that I received and five stars for their surprisingly good customer service.--------------------------Original Review below:BUYER BEWARE!I bought this several months so it's outside the return window. I've only used it about a dozen times for 30 seconds or less per use. Yesterday, during use, the blower made a quick pop and screech and then stopped working. The batteries were fully charged but just in case, I threw it on the charger again, but no change in symptoms. I wanted to know what happened so I tore it down hoping that maybe a cheap capacitor just needed replaced.As it turns out, the neodymium magnet used in the motor appears to be structurally weak. It cracked, spun apart, and seized the motor. No repair possible. The neighboring bearings are in good shape and show no signs of wear. I would also add that the blower is not assembled to be user repairable in any way. If you buy one anyway and it fails, and like to tinker, you might want to pull the three 18650 lithium ion batteries from the handle.It would have been far cheaper to have just bought a single can of air than to have spent so much money on an equivalent amount of air.

The exterior quality of this product is impressive, as it feels well-built and sturdy. I found the power to be quite decent, which was essential for effectively dusting off my computer. It performed exactly as I had hoped, meeting my cleaning needs perfectly.However, I encountered a major issue with the product. After using it only once and storing it away for six months, I attempted to clean my computer again. To my disbelief, the motor suddenly stopped working, and smoke started emanating from the device. It was clear that the motor had broken down, rendering the product completely unusable.Considering the initial promising performance and solid construction, I am disappointed with the sudden failure of the motor. The product's longevity and reliability are crucial factors to consider, and in this case, it fell short. I hope the manufacturer takes this feedback into account to improve the product's durability and prevent similar incidents from occurring in the future.Update: Reached out to seller, he/she was helpful and genuinely wanted to know more details of the broken product. Additionally, he sent me a new one free of charge. I’ll bring this back up to 4 star and will review again once I use the product some more.

Found the Blower worked Amazing...Was so Pleased with It...But after a Few Uses and after a Few Re~Charges, it gave up the ghost.Even though the light was Green, indicating it was Ready to Start.It just kept making a little Screeching Noise, and never Started Again!

Bought it a few months ago and used it about every 2 weeks to clean my keyboard, and every 2-3 months for cleaning the dust inside my computer.After a few uses, the power button to turn it on/off (the button that also lets you change the air strength settings) stopped working properly. It is no longer clicky and it's really difficult to use the button. It even turns off on its own and sometimes even turns on on its own while it was in a cabinet which could have been a fire hazard if I hadn't heard it.I loved this product very much until it stopped working properly. Highly recommend a Compressed air Duster, just not this one.

I recommend this product. Work very well and seems robust.

Works great. Only complaint - easy to accidentally turn it on - i do tech calls with this in my bag. Have to watch how i place it in the bag or it will turn on while in transit.
