Product review (4 stars): Combo NOT the way to go....
In reading these horrid reviews, I'm glad that I followed my gut and ordered my convection/microwave and oven as separate components.  I was concerned about potential fuse/board issues particularly if I wanted to use both ovens concurrently.  Plus, if one died what was I going to do?  I still have the look and space saving feature of a combo oven, but with ZERO issues.  I use my self cleaning feature all of the time and it works like a dream 5 years later.  We also purchased the dishwasher and counter depth fridge and have had no issues.
