I dont know why so many 1 star reviews, they were mainly bc it was missing a manual, that has nothing to do with the actual oven.  The other 1 stars seems like operator error.  Lol.  This oven is so easy to use.  And I LOVE how wide it is.  I can fit normal sized pans in there, muffins trays, small cookie tray.  I had this oven once already many years, it finally died (prob bc I used it so much lol), I went shopping for a new one and could not find any that were as wide, it was so disappointing, I found a few here and there that were as wide but they were ridiculously huge.  So I found out where to buy the exact same oven to replace the dead one and still love it.
