The toilet came on time; with everything in perfect condition. With the help of a good friend, I was able to install the toilet without any problems, as the instructions were detailed and easy to follow.  After the installation, I had a question regarding the flushing so I called Wayfair tech support.  Tom was very helpful, and referred me to Kohler.  The Support from both companies was incredible.  This is my first purchase through Wayfair, but it will NOT be my last.
