I just bought 2 of the O2Cool brand mister fans this morning at WM and both of them need to be returned. One doesn't work at all and the other the switch is all crooked and hard to turn off and on. So, be careful when you buy them that they work (can't tell until you get home and put in batteries) and save your receipt just in case. There was another type of mister fan, but they didn't have the carrying strap, my kids need it to be on a strap. I'm going to take a look at Walgreens and see if they have something.
