This clip allows you to use Bluetens without its original snap cable. Slide the Bluetens onto the wireless clip, then connect it to one of the special electrodes and apply it to your skin. Also discover the Surf electrode, small and oval, which allows you to treat pain in your joints or, more generally, all small areas of the body. In the case of the Butterfly electrode, it is perfect for larger areas of the body that may be difficult to reach, such as areas of the back. Bluetens is sold separately.
