When my predecessor wrote, the device would be too weak, then he has certainly forgotten to use conductive gel. Everything is solid and well thought produziert- also regarding hygiene and durability of "sensitive side" (conductive gel for use Wash from the rings, without this harming). The actual device has four programs that additionality via soft touch can be modified by "adjust". The strength of the stimulus can be continuously regulated from 0-9. That is the "gentle breeze" to the hurricane. Herantasten careful and not start with stage four; you can increase the attraction continually! Always plenty of gel use. It will also work just two rings: one for each pole or strand. A great and very reasonably priced device.
