We love our new oven.  The only design flaw we have experienced in this unit is the rack angle as you pull it out.  It tips slightly downward, which could be very dangerous if you had a lot of liquid in a roasted meat or vegetable dish.  The temp display does not tell you what the temp is as the oven warms. My old oven did this, so I always new what the oven temp was at all times. 
The touch screen had a kink in the bottom causing a wavy appearance.  I called Frigidaire, they instantly responded, arranged a replacement screen with installation.  I'm blown away by their customer service.  You just don't see support like this very often from a large corporation. I love Frigidaire!  I really enjoy my new oven.
