I have a TOTO (cambridge ma), but it has none of the fancy features. It did come with a sticker on the seat for
www.cleanishappy.com/ which sells the super toilet seat ad ons.
The toliet works well and uses very little water. It doesn't spin flush but instead uses a wave of water when flushing.
We got one of these for each bathroom because they are virtually uncloggable. They may not render toilet paper obsolete, but they do very nearly render the plunger obsolete.
