This is a great product. It heats quickly, the two ovens can both bake. The smaller, top oven, does tend to burn the top of the food when baking so there is some learning required to adjust baking time and temperatures. 
It is also nice to have the mobile app to see the status of the stove, get notifications on preheating, and seeing the actual temperature and not only the set temperature. 
The only real problem with the design is the material of the touch controls. They are so sensitive that any tap leaves ugly fingerprints smudge. No matter how clean your hands are, the slightest touch leaves a mark. If a smartphone screen was done this way, your screen will be unusable within 2 minutes. 
I would expect GE to use some anti fingerprints coating on the surface.
