It seems like a quality product
I just installed this after reading the generally favorable reviews here.  It seems like a quality product, and installed easily as described.  I did find the anchors included to mount the rail didn't hold very well in our surround; replacing them with some other standard anchors I had around helped some.  As noted by others, the included diverter does allow only one shower head _or_ the other to be used at any given time.
