Product review (5 stars): The oven was delivered promptly, and safely packed so ...
The oven was delivered promptly, and safely packed so that there  was no damages.  However, it was supposed to be the same as the GE microwave that I was replacing; unfortunately, even though much of it is identical, there were significant differences in the geometry of installing the oven.  This required much work in enlarging the space where it will go, and changing the support holes for bolts that support the oven.  It would have helped if the advertisement had indicated that there were differences.
