You need a Mystim Cluster Buster to use it.

Our Mystim Sultry Subs are true team players: Any number of them will obey their master, the Mystim Cluster Buster, and put out electrical pulses to one, two, three or an unlimited number of Mystim toys in order to pamper or torture you cable-free – just the way you want it. In order to be able to select different programs, you should make sure to use Sultry Subs with different channel numbers (1–8).
