We’ve only had the oven for a few months but so far everything is working well. I love the third oven rack and convection heating as an entire batch of cookies (one tray on each rack) can be baked at once.  I made a pork loin using the internal thermometer and it turned off the oven automatically as soon as the meat reached the internal temperature I set. Microwave works like a microwave should, and it’s nice to know I can use the microwave as an extra oven when needed for holiday crowds.  The fan does run on after microwave cooking but I have gotten used to it already. Convection cooking is new for me and this oven does it right.
