I upgraded to Cafe from GE Profile series. The buttons on this microwave is not efficient. You have to sit and hit +30 seconds A LOT if you want 12 +  minutes of cooking or sit there and turn the dial forever. This microwave needs a number pad to make programing the time easier. Because the door opens forward (not sideways) it is a real struggle to clean the back wall. Ours is above the built in oven and we cannot reach back wall of microwave because of the door design. Wish I could go back to Profile series. Not happy with this product and do NOT recommend it. There is also NO instruction  for the convection option. I have tried to find information online and it is not available; therefore, we never use the convection option. Very disappointing for the price.
