Query: Good will it lasted....

I bought this thing just to use while I sleep, and it functioned as advertised for about 3 months. However, it no longer even turns on anymore. I wish I could get a refund or have them fix it, but of course they make you pay for shipping.If a fan only works for 3 months when used only during the night, I consider it garbage. I have had cheaper fans that are still working after 10 years use...
