This is great, once you get it installed.  I had to cut out part to get around the water pipes.  It is NOT flexible, so it was an effort and hard to cut.  But, I measured carefully, then used a straight edge to score it, then was able to snap it off.  I reconstructed it and used silicone to seal it.  I have complete confidence now in case there is a spill or leak that my new cabinet is protected.
