Product review (5 stars): These are awesome, less than a month in only
These are awesome, less than a month in only, but they haven't budged.  The idiot who installed the previous dishwasher actually drilled small holes in the granite and used plastic yellow screw anchors which would fall out all the time and I'd have to replace.  Now my new Kenmore Elite dishwasher is extremely secure.

Highly recommend.
