Great value for the money. Not much guidance on how high to set it in the instructions so the jets hit you at the right spots.  I'm about 6 foot. My wife is 5 foot 6. Set the top 78 inches from the floor.  Seems to work pretty well at that height. You'll have to remove your existing shower valve and stub out hot and cold connections.  If you don't do DYI plumbing you'll want to hire a plumber for that part.
