Before installing my new Raritan PHII toilet I decided to actually read the directions before starting -- a first for me! Anyway, they talk about the above item in glowing terms. It appears to add a bit of Raritan Concentrate everytime you pump the head, which deoderizes the bowl and lubricates internal parts. Is this worth the trouble to install?

You read the directions first??? Wow!! 
Forget the TWK...you don't need it, and it's more trouble than it's worth even if there were any real benefit to it. Raritan Concentrate is a nasty chemical (quaternary ammonium compound) that's incompatible with non-chemical holding tank products, plus it's expensive and almost impossible to find...and the siphon check valve gets clogged up regularly.
