Just installed this myself, love the end result, no issues with operation or water pressure.  Works great, looks great.  Only reason for 4 stars and not 5 is the installation.  Two brackets must be screwed to the shower wall, then the panel slides down over those 2 brackets.  I installed over tile (not a perfectly smooth surface), and it was impossible to get the panel to slide down over the brackets that I screwed to the wall (i.e. through the tile).  I had to remove the brackets from the wall and bend them (with channel locks) away from the wall in order to get the panel to slide over the brackets.  That alone took almost an hour to complete.  I should have taken pictures to show what I mean.  You'll also notice in the pictures that I mounted the hand wand right to the panel (instead putting more holes through the tile wall), and I also used the Vigo fixed glass shower door, which was easy to install (but it's heavy!).
