We replaced and existing wall oven combo from Kenmore that was manufactured in. 2001.   This GE Profile was a nice upgrade.  Unlike the previous one which had swing open microwave door, I liked the pull down better.  Seems well constructed, and the stainless steel is much better look than the black I had.   My contractor swapped out the old one and put in the Profile with no issues.  My girlfriend and I started using it right away.  It was not hard using the controls which we found intuitive.  The selector wheel is quick and useful.  It reminded me of my Audi MMI selector knob.
