I think it's luck of the draw. I bought a dehydrator last summer at Aldi's was so pleased with it at first. I use it for making sweet potato chips for my dogs treats every month or so. Last week, I pulled it out & set it up. In the morning,there were half-dried chips & a dead dehydrator. I bought a better one, knew I shouldn't have tried a cheap one in the first place. So often the really cheap appliances break, it's so wasteful..
