Low rating for 1 overwhelming reason. Control touch pad is completely unreadable unless area is flooded with sunlight or, in evening or night time hours, you use a flashlight or turn on every kitchen light available. I've probably had 4-8 microwave ovens in the past 20 years, never had one this difficult to see the keypad. A function so basic and simple  should have been resolved long before going into production. I've seen this same complaint several times, it's not just my singular observation.
My bad for not recognizing this negative feature prior to purchase. G.E. needs to figure out a way to illuminate the keypad electronically or with brighter colors. At any rate this new purchase is going on Craig's List tomorrow.
