1. Controls are very confusing/complicated. Not intuitive at all. 
2. Very poor user instructions, even after a couple hour of searching online. Really needs step-by-step instructions. 
3. Tried an Advantium recipe from the included cookbook that sounded good, however, it took me an hour of exploring to find the area in the controls to set the cooking parameters. Then the recipe overcooked on the outside, undercooked on the inside. This is the feature I purchased it for, so I hope to be able to figure it out. Too frustrated to mess with it at this point. 
4. Regular baking works well, as does the microwave- the reasons for 3 stars. Otherwise, it would have been much lower. It is beautiful, but holy cow, I think I could have spent a few thousand less, and got something less frustrating to use.
