Product review (5 stars): Great clips to use for stone countertops
I bought these clips a while ago and decided I should wait a while before I reiew them in order to give them some time to see how well they fare.  I have marble counters and installed them as they said.  Simple process. I probably took longer than I should as I wanted to do it once and not try to move them after putting them on.  Even with that, it was about 15 minutes from doing a quick clean of the underside of the counter to having them attached.  I waited until the following day to actually attach the screws since I figured my kids would be too rough.  I've had these installed for many months (over a year) and they are still working beautifully!  Glad I found these as they help secure the dishwasher perfectly!!!
