Great size for smaller kitchen. The outside stays lukewarm but the fan pushes out the heat through the back. I pull mine out about 6 inches from the wall and it is about 5 inches from my upper cupboard with no problem. You have to make you own adjustments to some temps and time since it runs too hot as stated in some recipes. I turn down the temp 25 degrees and time about 20% less for the higher temp recipes. Toast works fine depending on moisture of the bread you adjust time. Fryer works great with the time lowered.  Baking worked great. It would be nice to have more recipes from Cuisinart but you can adapt. Size is perfect for 1-3 people or do more batches. Easy to clean, quiet fan. I have grown to love this compact little oven/fryer and now use it instead of my stove oven for most of my oven recipes.
