First the toilet is BIG.  Taller than most comfort height toilets. And I hate that it is only 1.28 gal flush.  It does not have enough water to fill the bowl so seems like it needs cleaning a lot.  Also half of the time it does not flush properly.  The round rubber flap hits part of the tube in the back so it just keep running unless I take off the cover and manually push down the flap.  Pain a lot to have it installed and do not have the box but would love to return it.  I just changed by stars to 1...I really hate this toilet for so many reasons.  The seat itself does not sit straight on the bowl.  The flush mechanism constantly gets stuck so I have to take the back off and manually fix it.
