Product review (1 stars): Good concept, but doesn't stand the test of time
I was a huge proponent of Granite Grabbers when I first stumbled upon them while doing a major kitchen refacing project. We were keeping our existing dishwasher and no side clips were available for that model, so undermounting was our only option. We installed them a year ago and had been extremely happy with the fact that we did not have to damage the underside of our beautiful soapstone counters with screws.

Fast forward to this past weekend when I noticed that the top shelf of our dishwasher was out of level while I was unloading it.  When I bent to investigate, I saw that the Granite Grabbers epoxy had completely failed and neither clip was attached to the underside of the counter at all.  I check them periodically, so I knew that this was a fairly recent occurence.

Sadly, when I contacted Granite Grabbers directly today, I was told 5 times within the phone call that if I purchased another set, they would send them out to me right away (um, well, I should HOPE so).  Because they were in use for a year and were "only" 10 dollars they couldn't warranty them - after all, 300,000 were in use out in the marketplace and he doesn't get complaints.  He did mention that they replace them when there is "user installation error" in the first few weeks.  So... 11 1/2 months later - at a 10th of the life of the average dishwasher - I now need to find another solution to keep my dishwasher from tilting forward out of the cabinet.

I recommend either expecting to buy these in bulk and replace them yearly or to find another solution for your dishwasher tilting needs.  Very disappointing customer service experience.
