I just got one of those this past week for my wife's home office. We have central air but she keeps the door closed and it doesn't cool off to good in that room. The one we bought works ok but not great just another one that works off water. 3 speed, mist and wait for it ...... different color lights ! Just what you need in a cooler ? She is happy with it but has it about two feet from where she sits. I think you are able to put ice cubes in it for better cooling. This helped so it was worth the little bit of money we spent.
