My unit was just installed few days ago. The sleek appearance enhance the kitchen remodel. The. Touch screen feature was very easy to figure out without reading whole manual. We only try using the broiler last night and everything seems to function as expected. The touch screen work good but does not function as great as iPad or iPhone (sometime require full finger touch instead of tapping). Other than that it works as intended. I have not tried the cleaning function therefore I can't give it a five star.
