Query: Piece of junk

After a few months, the heat of the oven melted the hinges of the glass door and warped the handle. I had to throw it out. Even when it was working, the toast, was not evenly browned, striped on one side and was very dry. This is the second product of this company which has given me trouble. I've learned my lesson.
