Question:
Do all your stim units output a bi-polar waveform with small width pulses. I've read that this delivers the optimum erotic experience, maybe?
Answer:
The pulse does not really have anything to do with the waveform pattern that the control boxes emit.
The pulse is the delivery mechanism.
The pulse can be changed from full on to pulsing almost like your heart rate and adjusted to anywhere in-between.
The intensity adjustment is the one that carries a waveform, this is the one that you feel, you can set the pulse wherever you need it, but the intensity determines what you will actually feel.
