I was a little disappointed that the first oven that was installed didn't work.  The interface display didn't light up or work.  The 2nd oven seems good.  Glad the air that comes from the vent isn't too hot since it is the height if a small child.  As with all modern ovens, they seem to take a while to preheat.  But still seems faster than the oven I bought in 2009.  Overall I think it's a good buy.
