We used them for our remodeling project four years ago. Holding up OK. You have to watch heat and steam getting on the doors directly. We had a bad experience when using the convection part of a microwave (ours is mounted over the range/oven) with cabinets above. We ended up changing the microwave to a GE Profile that had a better vent system as ours does not vent into a stack. Still, I had a stainless steel deflector fabricated and installed it on top of the microwave to further deflect the steam/heat out and away from the overhead cabinets.
I also heard that oven cleaning may put too much heat around the outside and could harm the doors. Not had that problem.
A friend of ours is remodeling their kitchen now and are going with solid wood cabinets based on our experience. If we had to do it over we would go with solid wood cabinets. Found the price is not that much different.
