Mostly a great toilet, but a single con dropped it down 2 stars.  I would buy a separate model from Toto again, but not this model.

Pros 
Stays clean longer than other toilets.
For most instances a single flush is effective.

Cons
Clogging can yield horrible results.  It has been clogged once -- my husband flushed an excess of TP after cleaning up a mess.  The toilet clogged, he wasnt able to turn off the water in time, and it overflowed -- getting water all over my bathroom.  Something to signify the toilet to stop to prevent the water from spilling over would have been great.
