I have 2 SmartBidet seats.  My first one is a SB1000 which I have owned for over 6 years.  It has served my family well and we really appreciate the warm seat on cold days.  Three years ago when we moved we purchased a SmartBidet100R for our spare bathroom.  We also took our original seat with us.  Both seats are working weill and help keeping us clean, warm and comfortable
