First, GE  claimed it would replace similar (Profile) oven.  however new oven is deeper and shorter so it cost another $200 to modify "opening".
Second, the temperature in the oven is not uniform.  I did several batches of cookies and the lower rack took much longer than the upper to bake completely.  I finally ended up switching cookies midway..a bit annoying!  My Christmas cookie baking "elves" are not going to be happy.
Third, I agree with another reviewer that the "beep" is not loud enough.  Then again, the old Profile was too loud.  
I am also not a cell-phone user, but the controls are pretty easy to manipulate.  I would have liked separate oven light control for upper/lower, but not a big problem.
Overall I am pleased-  let's see how long the electronics lasts!!!
