Product review (5 stars): Excellent solution - these should really come with your dishwasher!!!
Incredibly, this actually works.  I had no intention of attempting to drill into my new granite countertops and the Bosch dishwasher I have does not have a side mount anchor option so I was please when I read about this solution on some DIY thread as I was researching mounting options.  The instructions supplied say to attach the grabbers to the dishwasher anchor brackets then peel back a bit of the adhesive tape covering before sliding the dishwasher into position.  Wanting a tight fit, I peeled back a corner toward the front on each side so that the backing stuck out a bit then positioned my dishwasher, raised the legs until it was as tight as I could get it (there is play in the Bosch anchor brackets), then - using tweezers, got hold of the backing tape and easily pulled it off both sides before pressing the adhesive onto the underside of the granite and holding it as per the instructions.  Rock solid.
