I researched bidets for months before choosing the BB-2000. I chose this one because: 
1. I read in multiple places that BioBidet stands behind their bidets.
2. I wanted both a hot water tank for immediate hot water and on-demand hot water for unlimited hot water.
3. I wanted an internal pump because I have a well and want consistent water pressure.
4. I wanted high pressure, massage, and enema options.

I am glad that I took the time to learn everything that I could about bidets, because it allowed me to choose the right one for me. Now that we have hands-free toileting, it is unpleasant when we have to use paper!
