Clips for use with R7850 / R7880 / R7890. Please note that one clip is unipolar, and using both clips simultaneously makes it bipolar. The cable is split into a positive (+) and a negative (-) terminal for each clip. Important: Never leave two connectors on a single clip to avoid short circuits. Do not use if your skin is broken or irritated, if you have heart problems, or if you are pregnant. Tip: Use Rimba contact gel (ref. R3000) for best results. Features a 2.5 mm jack plug that connects directly to all Rimba Power Box devices. Compatible with R7850 / R7880 / R7890. Cable included.
