I've only been using this for a few weeks but this thing is awesome.  There are a ton of features I need to try but the microwave works really well and I've used both the convection oven to toast rolls, and the speed cook feature to bake some croissants.  They turned out great and I didn't have to preheat or use the big oven.  I can't wait to try to bake more things.  I really love that this is a microwave and an oven.  A little on the expensive side compared to microwaves but so far I'm happy with the money I've spent.  And it looks great in my island.

My 1 complaint is an esthetic complaint. I ordered this product from a big box store and their online photos match this site but the oven I received had a rounded handle instead of the more square handle that would have matched my other GE appliances.  I'm tempted to get new handles since this is a brand new kitchen and I really wanted things to match.
