I have to admit that when I saw the duster, I was disappointed because I assumed it was going be like all the other small cordless units I had tried previously. After charging it up, I learned the truth. It wound up like a small craft motor, and had much more power than I expected. I blew out both laptops and my ergodox, and they probably haven't been this clean since I unpacked them. Wow!
Highly recommend this little power house. It is much more convenient that a corded unit that might match its power.
This is overall a sufficiently nice duster for most needs around the desk. It's done a solid job on the PC's and keyboard I've cleaned out as well as on the general desk surface. My only complaint really is that it is rather loud for how much air it moves. While it's not leaf blower amplitude, it is certainly too loud for a workplace environment to not be disruptive and far from a significantly strong force. I personally don't need something ultra quiet, though.
Very powerful air duster, easy to operate and with a long battery time.
Both nozzles are handy and simple to put in place.
No compressed air cans for me anymore.
This thing blows air like it's a whore at a truck stop. It does what it's intended to do. My only complaint is that I wish they had a third setting that maybe didn't blow as hard.
Like a few other people have said, the battery is utter trash, and you apparently can't run it off direct power. I used it a couple times, didn't for a few months, and now it just doesn't charge or work at all. Dead within a year.
That is the problem, all units are tested before shipping, and the second unit we've shipped to you is also tested before the replacement. It is nearly impossible that both units arrived dead. You should try long-pressing the button to operate the product instead.
KeebmonkeyJust to update, it appears you have a problem with your batteries as others are having the same issue I did, batteries died and unit no longer functions. So I guess the impossible became possible. Do better Keebmonkey.
