As others have said they are all made by one company in China and private labeled for many brands. The Magic Chef brand I have is imported by a company that has acquired a license from Magic Chef but is not Magic Chef. It is just an import and sales company.
My first one lasted just under a year and the replacement (under warranty) just over a year. I repaired the second one with parts from the first one and it has lasted 4 or 5 years now.
Like many others we put the ice in a container in our freezer.
If this dies we will definitely get another.
