I purchased the Nickel shower head setup.  Installation is nearly as easy as a basic head.  You get to position the arms how you want them.  The flow is very good and it is very well made.  For the price, it is a nice unit.  I love the water flow from the head as it feels like rain.  I bought something similar in HD a few months ago and it is going in the trash.  This unit is superior in every way.
