This unique clamp features two gold-plated electrodes within the clip, so current flows across only whatever is gripped in the clip. It has an easy to use screw that allows you to adjust the gripping force so it is ideal for connecting to the more delicate parts of the body. The surface area on this one is quite small and thus gives intense sensations.
Comes on a 2.5mm or 3.5mm plug. Adapter to 4mm is available if needed.
