This was a replacement for the Supreme BB-1000 which lasted over 5 years. I like having the endless supply of hot water vs 30-45 seconds especially in the winter. It was a breeze to install and fit perfectly on my 1 piece Toto. It is surprising how reasonably priced this unit is compared to the more expensive brands. Why would you spend thousands when the BB-2000 does everything you could possible need. My one complaint is that he remote does not have a back lit screen  and the temperature settings for the water and seat are not color coded like the remote for the BB-1000. Other then that, perfect.
