The toilet itself is attractive but after 3 months of use, there are two serious issues.  1. the low flow is great and it gets 99% of the waste down but leaving 1% is not sufficient in my book. 2. and most importantly, there is nothing in place to stop an overflowing toilet.  Two nights ago, unbeknownst to us, the toilet stopped up and overflowed for an hour.  It flooded our bathroom and the kitchen below.

Added 1/31/2019 - Today the toilet flooded my house again.  We found out it was not "stopped up" but the button got stuck.  Unfortunately, it destroyed the ceilings and rooms both on the level below but two levels down as well.
