Less than a month into this futuristic combo wall oven, no complains, The features are endless with a comprehensive and simple to use menu loaded with programable presets. I was up and cooking upon DIY installation. The four star rating for the GCWM24423200  was given simply because the top oven did not have the Air Fry feature as did the Botton oven. Would have given the Five star rating if not for this reason. But still  extremely happy with it.
