The product installation was very straight forward.  The installer warned us about starting for the fist time, the grills will create an odor.  So we ran the ovens for 30 minutes and no other odor occurred after that.  Glad that was mentioned.  We are still learning the top oven that has the convention feature.  We are still trying to learn the new method of cooking.  Would like to see some guidelines on how convention effects cooking and what we should look for.  So far both ovens are great and love the feature that you can connect your phone and monitor the cooking process.  Also like the additional phone app that comes with other cooking ideas and suggestions.
