Query: Good Bye Kitty!!! Disappointed Kitty!!!

Got the "Hello Kitty" humidifier and just loved the looks of it. However it only worked for 1 night and a few hours, the second night it had stopped when I woke!I am really bummed, because I could feel the difference it made.So this one goes back, but maybe I'll try and reorder again, as I need one. From the reviews a few other people had to try more than once to get a good one!I usually have no complaint with the stuff I buy here and I am a very frequent customer, so this is unusual.So anyway just for FYI
