I bought this bidet via the Indigogo crowdfunding, and I'm so glad I did.  It fits my toilet, and was incredibly easy to install (easier than my showerhead, if I'm honest!).  The only downside I'm having is that there is only a little difference in the locations of the sprays for female and rump.  As a plus-sized person, I have to rearrange myself to get both areas clean.  But even with that, this was well worth the purchase.
