Have only used for about a month, however seems to work just fine in all operations. Probably need to fine tune my use but as I get acquaited with the Oster I am sure the quality of what I use it for will be better. Lot of frozen products do not give use for a toaster oven except when to tell you not to use one. I use it more then heating up a large oven for such items as a single biscuit, pocket snacks, broil fish and such. Handy little item. I recommend this item if looking for a toaster oven.
