I was a bit skeptical at first, there were a few items that I was just not used to including the increments of 25 degrees instead of a finer degree of control.  Interestingly that hasn't effected cooking at all.  We have had consistently even results from pizza, chicken, tater tots, nuggets, cookies, pie and brownies.  One big plus is that it is quite and cools down much faster than our previous double oven.  The air fryer works great and the one time we used the no preheat it worked out great.  I'm really loving this oven
