Product review (5 stars): It worked (so far) will keep updating after a few months
My granite installer messed up by drilling too big a hole on one side. Thankfully, I saw this product and ordered it. I have followed the installation instruction without any deviation - did clean/clamp as instructed. This has really worked out great - it is only a week since I have installed this. I will update status after 6 months on how this product has faired.
