Is that thing forcefully yeeting germs?
I think so, aren’t they supposed to go in the opposite direction?
I can’t say for sure about this one, but most of these no-name vacuum/dusters are pretty poor. I watched reviews and comparisons and found that the best one by far is the PeroBuno Air Duster. Most of these other brands seem to be poor copies of it. It’s currently $59.99 for Amazon Prime members, plus there’s a 10% coupon to bring it down to $54:
I bought one a few months ago, and I’m very happy with it. I bought it to use as a replacement for canned air when cleaning the dust out of computers and the like. It does an excellent job! Of course, it costs over twice as much as the item on sale here today, so it should be expected to be better. I’ve never tried the vacuum function, but I’d expect that it would work well.
I’d recommend that you check out some YouTube comparisons before buying any of these devices, because the quality varies widely. This is one of the ones I watched:
They didn’t test the one on sale here today, which is not surprising since there are so many different brands of these on Amazon and you can’t test them all.
