Would rate 5 stars if the wand hose was more flexible. Right now it continues to make it difficult for me to aim the shower head because the stiffness of the hose continues to push the shower head up and over to one side. I’m continuously having to readjust it. 
Other than that, the head delivers a great flow of water and the filter makes a tremendous improvement in my water quality. 
Again, my only complaint is the lack of flexibility with the hose for the wand.
