My husband removed our old oven and installed this model, no problems and we did not loose any cabinet space! It does take longer to preheat than the old oven and, in the top oven, the element is very close to the rack, be careful of burns! Also, I have not quite mastered adjusting the racks to different levels, but I am working on it - haha! I LOVE the touchscreen programming, having TWO ovens and the time-bake settings! It's just the two of us at home now so we mostly use the top oven which I feel is much more energy-efficient than our old oven was. I recently hosted a bridal shower and having two ovens was a game-changer! I don't know how I survived before with just ONE oven!!
