The Analiscious Pulsatron accessory looks identical to the standard Analiscious, but because it is controlled by the Pulsatron, comes with a staggering seven functions. We recommended the Analiscious as a standard product - as a Pulsatron accessory, it`s a world beater. (N.B You must either buy or already own a Pulsatron or Mantric controller to use this product)
