It looks great.  It's plastic and I hope it retains its finish
This can be a bit confusing to install. Coupled with the recommended Delta valve I could not completely get rid of a bit of friction between the handle and the chrome barrel that goes over the barrel of the valve.  Kind of a wonky assembly (with the chrome barrel cover) going through the trim plate. 
One problem you'll likely see in reviews elsewhere is the flow restrictors.  There's one before the shower head.  It's easy enough to remove if you dissemble the articulating joint and push it from behind.  
There are two more restrictors in the hand held unit.  Remove the hose and the first one is easy to remove by simply starting a screw into it and pulling it out.  The second is set a bit deeper and I used a stiff wire with a small 90° bend at the end.  I was able to snag the restrictor with the bent end and easily remove it. It makes a big difference.
