After having my previous Frigdaire electric oven for 16 years, a very simple no thrills oven this has been just a little bit of learning but I'm excited to try the new features.  I cook at least 7 meals a week and depend on my oven as I don't do simple pop in the microwave reheat meals.  The preheat feature does seem slow but I never had a digital display telling me the oven rise in temperature as it does.  Nor am I used to the fan option always on but I am willing to expand my learning and hopefully, get close to sixteen years of service from my appliance.
