Product review (5 stars): Well worth it
Was able to purchase at local store (Lowes).  Correctly adjusted the positioned of the dishwasher and then slid the granite grabbers in place. I was even able to do some minor adjustment of the grabbers before the adhesive really took hold.  This made installation very easy.  So far they have worked well,... no more movement on the dishwasher when the door is opened or closed!
