I love the oven, features, and speed; so much, that this is my second.  My other was left for the new owner of my sold home (lucky them).  My only issue is with the installation.  I do not have an overhead cabinet (older shore home).  There is no accomodation for this.  My work-around was to use steel pipe straps from the wall behind the top of the oven, to the under-cabinet mounting holes.  Unfortunately, the bolts needed to be shortened as well.  MINOR cost that could be incorporated in the mounting hardware from GE.  Will add photos later.
