The beautiful, innovative stimulation device is made up of a remote control and a remote-controlled receiver. up to 8 mystim toys can be controlled at the same time with the included receiver (sub). the receiver can control the different programmes and intensities. the amount of toys that can be controlled simultaneously increases with every sub (please order separately). therefore in theory, an unlimited amount of devices can be connected at the same time. there are 10 intensity levels, 12 stimulation programmes and 5 special training programmes (e.g. for the pelvic floor muscles) in total. the clear display and the buttons are lit up and this means that they can still be seen in a darker room. the mystim cluster buster comes in a beautiful storage box. a remote control, a receiver, a bi-polar electrode (self-adhesive) and an instruction manual are included in the delivery. the lithium-ion battery can be recharged with the included cable.
