We have had our KitchenAid for probably about 20 years and it is still going strong. Probably does need to be replaced soon though as there is a small rust hole on the bottom of the oven and also it is starting to have some issues. For example, the display went out a couple months ago so it doesn’t display the time anymore when off BUT when it is on, it still displays everything, so idk. Also over the summer we did have an issue with it, showed the temperature/thermometer icon, and was having some issues, but it seems to have fixed itself. So very minor things but still very much functioning after 20 years. But it is pretty dirty/filthy and starting to have minor issues as mentioned so likely needs to go. It is a double oven and in the wall but we rarely ever use the bottom oven. Mostly just for storage now. We did use it some when we first got it and occasionally but very very rarely as we never really have people over anymore ha but they definitely don’t make stuff to last anymore. Probably stopped 10-20 years ago. This oven was probably one of the last made to last things. Kind of don’t want to replace it because it is so good.
