This is a step up for our household from a simpler model toaster over. It's easy to use and is used as a second oven. Even Heating Everything has always come out hot all around and crisp. Nothing has ever been hot on one side and cold on another. Safety The timer counts down and then it automatically shuts off. Also if you don't set the timer the over shuts off on it's own which is wonderful. The top of the oven does get extremely hot so I don't recommend putting items on top of the oven to make sure nothing catches fire. Ease of Cleaning This depends on how quickly you clean after cooking and a mess is made. I recommend putting a over protector at the bottom to help cleaning. Durability We use ours every day multiple times a day. The glass door is durable after being dropped down a few times instead of set down gently. Design I have no complaints. The stainless steel matches our other appliances perfrctly. The over is wide enough to fit a pizza stone inside.
