I have used every feature of this oven, microwave, convection cooking and speed cooking all work well.  The installation was easy and it looks terrific. One of the main reasons I bought was to have a second oven as well as a microwave.  When I used the convection setting the turntable still needs to turn.  I wanted to warm a ham but the weight of the ham caused the turntable to get stuck.  Still, all the rest works well.  I wish the turntable was more powerful or simply not needed for convection setting.
