I was so excited to install these (just remodeled the entire kitchen and got all cafe appliances). The first thing I discovered was the the App was VERY frustrating to use and would glitch and close out. Secondly, I looked everywhere for instructions videos showing all the fancy features and how to use them. Nothing. 
OOOOH, and with all the appliances now on my wifi, I can't even watch a movie (we live somewhere were good internet access is a struggle). So now I've had to disable that feature which was one of the reasons I purchased the appliances!
The first time baking bacon in the oven it burned on one side and wasn't fully cooked on the other (tray placed horizontally in oven).  Overall, I expected more from these appliances and GE.
