I was referred to this company for a granite counter installation. As the install, they did not use any clips to install my undermount sink.
When I questioned them, they advised that the silicone would hold without failing. A few months, the sink dropped from the counter. For months I have been contacting Frank from APR to get it corrected, but they have never contacted me back.
Would absolutely recommend to go elsewhere. It seems that once they get paid, they is not after care for any customers.
UPDATE: (was away for a little bit and unable to update)
They did arrive on Monday (the first weekday after I contacted them on the weekend) and corrected the issue. The original caulking did not fully adhere to the sink (as explained by Frank - it may have been some oil from the manufacturing of the sink that was not fully cleaned) and it was clear that there was NO bond between the counter, silicone and sink from the original install at some portion of the sink lip).
The correction seems to be ok, but I suspect only time will tell how well it holds up.
One additional note, I was quite persistent about installing clips, however Frank advised that they do not install any clips onto granite counters as the weight from the sink may crack the granite around the screw holes.
A little more communication from the company would have them with 5 stars, but other than that, great.
