Product review (3 stars): Great At First
This worked really well for five months, and then failed.  Good customer service from the company--when I contacted them to ask about what to do, they immediately sent a response with some suggestions that don't involve their product.  This product was amazing at first--I just wish I had anticipated that the granite grabbers might not be a permanent solution.  My review is therefore meant to make people aware that they should anticipate and have a plan for fixing it if the product fails at some point in the future.
