We installed our new micro/oven just about 2 weeks ago now. The microwave portion of the unit works very well and is reasonably easy to figure out. I use the fast keys alot. I do find that using a lower power setting than 100% is not the most intuititve to program in. I still need to refer to the manual for this. The oven portion works well too but it is even more confusing how to use it. The instructions are not easy to figure out and I have a university education. I would have loved some 'how to videos' and calling customer support was not helpful for this request. If you are patient on learning how to use the appliance you will like its small size (for an oven) and convenience of having the micro built in. You could easily get away with this unit as your main oven if you had a small household.
