Product review (5 stars): Worked Great!
Our dishwasher was installed 12 years ago and it was attached with white silicone. Since it was attached to the porous underside of the granite, it would be almost impossible to get rid of all that silicone and allow something else to adhere to it. But these granite grabbers attached away from the  old silicone and stuck well to the granite. It's a little sketchy after the tape comes off the grabbers but I got it lined up before with the tape attached and MAKE SURE the door closes and you are in business to permanently attach it!
