This oven came brand new with purchase of our new home. Overall, I’m unimpressed and would love to save up and buy a better oven. My biggest disappointments are: 1. When using the convection feature, the left side of the oven cooks faster and will turn brown before the right side is fully cooked. I bake and sell cinnamon rolls, and I have to switch the pans halfway through the bake time to get an even cook/color. 2. When the convention feature is on, the front of the oven cooks faster. 3. A MAJOR frustration is setting the timer. Once it gets to 10 minutes, it starts jumping 10 minutes at a time, so setting the timer for anything between 11-30 minutes requires you to stop, and start again to keep the timer from jumping. I wish it had a 0-9 number pad where you could type your time and oven temp.
