I bought this at the end of November. I loved the cool mist and the quiet operation. It started leaking slightly around the base after two weeks of use. I thought perhaps I hadn't seated the tank properly, so I kept using it. After another week, the leak around the base became much more pronounced, draining 1/4 of the tank each fill. I had to quit using it and contacted the supplier. The warranty in the documents say if it starts leaking, throw it out and there is no recourse as it must be a user error. They finally responded to me this week. You need the original packaging and receipt in order to get any satisfaction from them. Unfortunately, I didn't save the packaging so I am SOL.
