Product review (2 stars): Did not work as advertised
I purchased the Granite Grabbers on 12/7/15, installed shortly after. As of 1/6/16 one of the mounts has released from the granite. I followed the instructions to the letter. I would have to say that I am not pleased with the product. I am going to have to try Gorilla Glue and see if that holds. I guess that product is a nice idea but does not work in reality
