Does not cool as well as I had hoped. I had pretty high expectations from the reviews and ratings, but I'm left disappointed at it's performance. Did it shoot out cool air? Yeah, technically it does... but the small size means that you won't feel it unless you put it right up against your skin. If it were larger, it might make more of a difference, like the size of a medium-sized mini fridge, but with it's small footprint, it's on par with putting a glass of ice water in front of your desk fan. In fact, if you have a large-ish humidifier that shoots upward, you could probably get just as equal results, if not better, if you filled it up with ice-water and put it in front of your fan to blow cool air into the room.
I also disliked that it left water marks on the fins or grill or whatever it's called. Maybe it won't if I used distilled water instead of tap water (it said I should use tap water), but going that far should be unnecessary extra step that's too much of a hassle.
Bottom line: I sent it back for refund. If you buy this and happen to get a unit that's has some noticeable water marks on the fins...sorry, you probably got mine. I did try to clean it, but it's impossible to clean the inside, so best I could do was wipe the outside down with moist paper towel.
