I always had a double oven and rarely used the small one however in the last two houses - rather kitchens I have remodelled, I have had a European convection/microwave (no turntable) installed.
I now rarely use the large oven, and particularly as my Neff small one has pyrolitic cleaning and I just turn it on and it cleans itself like new!
I would never buy that double oven again after having worked with this type as they are quite large for two people and fit a few dishes in at a time and you can do micro/convection together which is great.
so, I DO have two ovens, but one is a combination of microwave and oven.
I have 2 ovens similar to the pic, but I only use one, I hate cleaning ovens at the best of times, let alone have to clean two of them, and what's annoying is I can't seem to have much luck getting the glass stains off.
I wish I had 2 ovens. Even though my children have left home I regularly bake meals and cakes for them and would love the luxury of having 2 ovens to cut down on cooking times. We spend a lot of family time at our house because of the room here compared to their homes.
