I purchased 3 Swash 1000 Bidet's for Christmas presents for my wife, parents, and mother/father-in-law.  Not the traditional X-mas present but after installing the words out of my wife's mouth was "best X-Mas present ever". 
Other than installing a GFI outlet behind our toilet, the installation of the Swash 1000 was simple.  Operation was easy and we love our new bidet.  Left town for a week and really missed it.  We will never go back to a toilet w/ no bidet, in the master bathroom again.
