Better than I'd hoped.  Key components are metal (not plastic).  Gaskets and orings seem pretty sturdy.  Installation was a breeze - didnt even need the pipe wrench.  
Head can be angled in rest position- good for small showers because you can start it aimed at the shower wall (minimize floods).
Magnetic snap in holds the head firmly, but not hard to detach it when needed.
Change spray modes by depressing the little switch on the handle.  Wonderful feature.  No more spraying in your face while tring to twist a large clumsy dial.
