We've had this Rival CO606 Toaster oven for 2 1/2 years and were generally pleased with it, except for occasional weird squawking noises from the convection fan, and for the lack of any way to turn off the convection for normal baking. We especially liked its ability to handle a 12" pizza, which it baked very well. It also performed well at toasting, baking small casseroles, pies, etc. We never used it for broiling.However, one of the calrod broil/toast elements burst with a blast of white light while toasting, and I have been unable to locate any source for replacement parts. No one expects things to last forever, but our previous toaster oven lasted closer to ten years, not 2 1/2.
