I bought the BB 2000 a week ago, it arrived today and was super easy to install.  My guess is the most difficult part will be installing an outlet if none are near your toilet.   After working with my friend/neighbor, who also purchased the same unit, and successfully installing gfi outlets in both our bathrooms, we assembled our bidet.
  Outstanding product that met all its claims.  Soothing heat both in water and seat temperature.  The functions and remote worked perfectly.  My neighbor said the same for his unit. Double thumbs up for anybody considering a purchase.
  Final note, solved the toilet paper crisis and no worries over the hoarders now.
