I purchased two and had them professionally installed by a very experienced Plummer.  I recommend a HIGHLY EXPERIENCED professional plumber install this. DO NOT HAVE A JACK OF ALL TRADES HANDYMAN FROM CRAIGSLIST do your install (may be too difficult depending on the age of the homeexisting plumbing line placement). Also, have your Plummer inspect the product and your home PRIOR TO CLOSING UP THE WALL to confirm placement of pluming lines and valve compatibilityfitment.  They are beautiful and very functional. The only criticism I have is the flexible hose cover for the hand wand is plastic. Not a deal breaker, just annoying. 
It’s like plastic “wood look” trim on a high end luxury car. The whole family loves this shower!
