Product review (3 stars): Adhesive did not hold to granite
The adhesive did not hold and the mounting brackets came off after about a week.  To be fair, the tabs on my dishwasher probably exert some downward pull on the brackets.  I am in construction and after consulting with the seller, decided to try bonding the brackets to the granite counter using a two-part epoxy that we use to bond rebar onto concrete (first remove all the original adhesive on the brackets). So far it looks to have worked.
