Great looking toilet, clean lines, easy to clean, water supply hidden behind and bolts covered inside of the toilet, which is for me the best feature, as everyone knows is annoying to clean. 

DIY Installation is a little more challenging because of weight and blind setting of flange T-bolts. I marked the floor and toilet with painter's tape to help align and also used a shaving mirror on back wall. I placed the nose of the toilet on a towel to help with weight while maneuvering Fernco wax free seal onto flange and while lining up T-bolts. It went fine. The provided tool makes tightening nuts onto T-bolts easy and the other end of the handle is made to tighten a 3/8 inch supply nut. You need all of 12 inches for install off back wall and the supply pipe should be no longer than 6 inches.  Fast delivery and double box packed, came in perfect condition.
