My son bought this for me. He had bought one BB-1000 for me 7 years ago. That is still in full function (with just some minor quirks, which just started). But it lasted and I happy with for the last 7 years. So I asked him to get me another one and I got this BB-2000. I love this unit. I would highly recommend Bio-Bidet compared to other brands, which I bought and had to return due to problem.
