2nd GE, upgraded to this from a 12 yo convection/microwave. It does a great job on all that I have tried so far with one exception. Re the sensors, I have only used the beverage one so far. It likes to boil my coffee, so I don't use it; instead I time it myself and watch it closely. LOVE the dial and the LED light. I'm 5'6" and I have to get on my toes a bit to see in as the oven window blackened portion blocks my view. Also, I have NO CLUE about how to change the filter as that's not covered in their info sheet. Operating in the dark as the instructions provided are very basic/confusing, however, the buttons do walk you through things though. There is NO MANUAL online, so don't bother to look. GE, please provide a manual!
