And, here's my personal review (unfiltered, you're welcome):
GOOD THINGS-
Heated Seat. What a luxury! This is worth it, worth it, WORTH it in my opinion. So nice to be spared the "Oh my God, that's COLD!" reaction.
Heated Water. Important for the same reason above
Adjustable pressure/pattern of water spray. After all, no two bodies are alike.
Programmable personal preferences. Once you find what works for you, it is a simple push of a button to get to your programmed preferences. Different users, different programs.
GOOD TO KNOW-
I say "good to know" because I don't have any "bad things" to say -- just some things that are good to know that you won't know unless you experience them or hear them from someone who has (and who probably does more research on toilets than your average friend, no?).
The adjustable nozzle position is important. The one I tested did not have this feature. I found myself having to sit differently on the seat. This was not that big of a deal for me, as I am small and able-bodied. However, if the user does not have the same ability to move around (or doesn't want to have to think about changing a habit that has been formed over a lifetime of toilet-use), then the ability to adjust the position of the nozzle is important.
You will still need toilet paper. The washing and blowdrying does a very good job, but you will probably still need to use a small amount of toilet paper. Water alone will not get the job done. This is something to be especially aware of if you are shopping for someone who has difficulty with the dexterity required to self-clean. It should reduce, but not completely eliminate the need for periodic nursing assistance. Again, without a little toilet paper, you will not be squeaky clean.
