Product review (3 stars): Inspect it Carefully!
It was quite easy to install directly over the tiled back splash. I left the protective coating on the panel, peeling back just enough at the corners to allow me to insert the stainless steel screws (which I had to buy separately).  However, I noticed a small dent a couple of inches from one of the ends after peeling off the rest of the protective coating, so I had to uninstall it and flip it top-to-bottom, hiding the dent behind the range. I would also recommend using some construction adhesive to make the panel stick evenly to the wall.
