We have a DeLONGHI toaster oven that is well over 10 years old and have never had a single problem with it. In fact, it has pretty much outlasted all of our other small appliances, and it literally gets daily use. My parents' model, believe it or not, is over 20 years old! I've looked into different DeLONGHI models because if ours does ever conk out, I'm sticking with this brand. One reason I like this particular model is because it is large enough that you can cook two pizzas in it at once, or you can cook a main dish and side dishes at the same time. Another plus, of course, is the convection heating, which cooks food 30% - 40% faster with even distribution of heat. This model's interior is also all non-stick, including its racks as well as the bake pan and broil tray that come with it. Finally, another thing that would be a step up for us from our current model to this one is the interior light, very handy to have. Be sure to VOTE THIS REVIEW UP if it has been of help. Thanks!
Although it does take some time to warm to the desired temperature, this is a very robust and effective appliance.
