Pinwheels or 'Wartenburg' wheels, were originally designed to test nerve response...ours tests a little more than that. The spiked rotating wheel can be drawn up and down the skin to generate a wealth of sensations - and that is before you even connect a powerbox.
The pinwheel is fitted with an insulated handle and a single heavy duty 4mm socket. Connected up together with another contact point (the single pinwheel is a monopole electrode) the single spiked wheel will tease and torment the skin of your subject - a fantastic sensation.
As this is a monopole electrode it can be used on most parts of the body, but care needs to be taken to ensure the path between the pinwheel and the second contact point does not cross the chest, and do not use to stimulate areas above the neck.
we strongly recommend the use of conductive gel, pinwheels on dry skin just don't work as well.
