Product review (3 stars): Doesn't mount on a GE Profile microwave without modifications.
The tabs located on the bottom are designed to fit into a slot in the microwave, then slide over the grille a bit to fit into place. However, the tabs on the unit don't lineup on installation with a GE Profile Microwave. The top tabs do line up after the bottom tabs are removed to allow the grille to slide over an additional 1/4 inch or so. I doubt this will hold up with only the top tabs mounting correctly.
