I wish this could be used as a dual shower but you can only use one shower head  at a time. Weve had this for over a year and its worked well, however, the suction that holds the hand showerhead keeps falling off all the time. There is no rusting taking place and overall it is good. However, only 3 stars because weekly Im trying to stick the hand showerhead on to the wall.

**update- after a few years of having it I will be replacing as the suction continually falls off of the second shower head
