I haven't used it much yet, but so far it's just what I was looking for. I've used it for blowing out keyboards or dust from places a duster can't get to. I also used it on filter screens (from and air purifier and heat pumps) after I washed them to get them dry faster. Blew out all of the water that gets trapped in the fine screen squares and they were dry in no time!
My only complaint so far is it isn't super intuitive. For example, my ginger lands on the button for the LED light and I get light instead of air. Not a big deal, just a bit annoying.
Not sure how long it will last but so far it's a solid purchase.
