We replaced a 32-year old GE double oven with this one and had high expectations for it based on the reviews we read. Never had a service call on our original oven. Here's the reason for the mixed review. first the good. We bought the oven and had it installed in preparation for Thanksgiving. Thanksgiving day was the first time we used it. We cooked a turkey in the upper convection oven, which turned out delicious. We used the oven thermometer and set the timer - the turkey was cooked perfectly in the time allotted. Now the bad. We used the lower oven to cook several side dishes over a period of 40 minutes. After placing a covered dish in the warm lower oven, the interior glass shattered spilling glass all over the bottom of the oven. Thankfully the covered dish was not affected and we used the upper oven to finish heating it.
