The cooktop is great especially the ability to slide between elements. When using the oven I find the touchscreen to be too sensitive. If you brush against the screen any setting gets cancelled as it changes to what ever is touched.  I thought the “new” setting would revert back to the previous one if you don’t push Start. Unfortunately not. 
We tried unsuccessfully to use the Convection setting. The temperature was never achieved. We eventually selected a bake setting.
