Question: One of the reviews mentions the handle is plastic. Seriously?  A solid brass diverter valve and the flow control handle is plastic?
Document: Both, and just [rainfall] shower head - work perfectly. But trying to switch to just the hand held showerhead (I forget if it's the middle, or bottom setting) doesn't work. Have checked the mechanism and water flow is fine, as well as the valves. Water just gets closed off totally when you try to switch to the handheld..
Works exactly as intended and pictured. Was very easy to install, just make sure to use plumber's tape. I didn't use it on the first install and it leaked water (silly me).
Answer: no
