Our Mystim Sultry Subs are real team players: Any number of them obey their master, the Mystim Cluster Buster, and send electrical impulses to one, two, three or an unlimited number of Mystim toys to wirelessly pamper or torture you, just as you like. To be able to select different programs, you should make sure to use Sultry Subs with different channel numbers (1-8).There are no limits to your imagination and your love of experimentation with the Cluster Buster & Sultry Sub. Whether you want to bathe in gentle tingling for hours or let yourself be driven to ecstasy with brisk pulses in the right place - it will pamper you from tender to intense to hard. Are you open to new things? You can choose between twelve stimulation and five training programs. For example, you can also make the pelvic floor fitter, which is particularly challenged during lovemaking. One Year Warranty.
