UPDATE: The seller contacted me, mentioned the air duster/vacuum was still under warranty (I then read the User Manual and saw the warranty info in it!!), and asked if I'd like a refund or a replacement. As I liked it, I asked for a replacement, and it arrived in a couple of days. I'm impressed they were this proactive, what an honorable company, and they didn't ask me to amend the review, a classy action, but I'm going to, anyway, as I am really pleased with the unit.Here's my new review:I like this little vacuum/duster very, very much, it's useful--grounds from the coffee station, crumbs on couches and carpets, escaped kitty litter, dust bunnies that mysteriously appear, and so on. Much handier and easier than sweeping or hauling out the big vacuum, especially on stairs. I automatically plug it in to recharge after each use, saves making a decision. It hasn't run out of battery on me yet, though the longest I've used it was about 15 minutes.I can't understand the complaints about it being underpowered, I find the suction very strong, much more so than others I've tried. Maybe those folks don't realize it has three settings, one push gentle suction, second a bit more, and the third is strong.It only took a couple of uses before I was in the habit, and didn't have to think about it anymore, of pushing up to turn on, push in on the opposite side for degrees of power.This is one of the best purchases I've made.ORIGINAL REVIEW: Didn't use it until about a couple of weeks ago, had been using a bigger handheld vacuum. Decided I wanted to use it to blow dust out of the corners of the windowsills, and it worked OK, then started using it in the mornings to vacuum up kitty litter the litter rug hadn't trapped, pet hair, scattered cat food, and so on. I liked it until my fifth use when the little flapper came off, I didn't notice that, and it must have been thrown into the trash can with the contents of the mini vacuum. I presume it was sucked inside the vacuum as it wasn't anywhere on the floor. Didn't notice it until my next use, and there was no way I was going outside and climb into the dumpster to start searching for it!
