I studied bidets for six months before deciding on BB-2000.  It has more features than all other bidets, everything you could want for comfort and cleanliness.  Everyone who comes to our home has to try our bidet. They all love it and are excited to get one just like ours.  I don't like using a regular toilet when I'm out and about because I never feel as clean. We have had our bidet for two years and have not had one problem. The instructions are easy when  installing.
