I used this replace a very old and outdated sink in our home.  This sink was far larger than the previous one we had, which meant some cutting of the countertop.  Not only did the template provided work perfectly, the entire install went smooth from the product's end (I had to replace my very old shut off valves which was entertaining - but that's on the home's end, not Kraus').  Overall, my wife and I love this sink, as does every person who sees it.  We just hosted a 16 person gathering last night and this sink handed the onslaught of dishes and cleaning excellently!  Makes us wonder how we ever did without it!
