Bought this last Christmas and it has been fabulous.   Initially had some problems with cooking temperatures and called for a service tech, which came the next day. The   Tech showed me how to go into the ovens menu system to adjust it.  After I read the manual and adjusted the offset in the oven operating range it is working to perfection.  The convention roasting browns the food fast and seals in the juices.   Could not ask for a better oven and service to back it up.
