Conductive gel is a MUST for ElectraStim external electrodes. Without it, stimulation can feel prickly and unpleasant and in some cases, you may not feel any stimulation at all. You only need to apply a pea-sized amount to the contacts on your external electrodes, so this 60ml tube goes a long way.
You do not need to use the gel with the Pads or with internal electrodes.
