I'm looking for a hand held pulsing shower massager that is easy to
disassemble for a complete, thorough cleaning and has a flow restrictor
that is easily removed. It should have a strong massage setting. That's
all I use. Otherwise it takes forever to rinse the lather out of my
hair.

My 8 year old Waterpik hand held shower head just died. The ring that
changes spray settings rotates freely (it shouldn't) and the water is
coming out all the holes in a feeble way, so it's useless. In the last
year, I've had to clean it frequently by soaking it overnight in
lime-away, so maybe that destroyed it.
