Product review (3 stars): Didn't Work For Me
It was not the fault of the product. The gap between the top of my dishwasher and the bottom of the granite counter was just too large (a full inch). I took a chance buying it because the listing gave no idea about the actual size of the bracket. When I saw that the gap was too big, I tried bending the bracket upright to make it fit. It held on valiantly for a few weeks and then gave up the ghost. I think you would be okay with a half inch gap or less.
