LOL! I have one you have to defrost manually and when I used it it had to be done very often. Friends gave me an old one of theirs that defrosts itself, so the manual one is now a storage box for yarn! It's unplugged of course. I still don't have a stove, or rather it's a storage box too. It became unsafe to use, But I have a microwave and crock pot and toaster oven and electric skillet and a burner you plug in. So I do well!
