It works: The glue of the electrode can absorb water. The gel is likely to be water with minimum ingredients of a gelling agent. I tentatively pushed a small pile on a glass plate. After a few hours everything was evaporated down to a fine, hard, colorless layer.
My application is to improve the skin contact when searching for the motor nerves by means of contact-pin (motor-Pen) for electric muscle stimulation (EMS or TENS). The gel is well suited to. However, one must not be too long, since the applied gel film evaporates pretty quickly on the skin. Then one notices nothing of the fine residues.
By pressing bottle with a fine closable opening at the top, the gel can be easily removed without spilling. When Compex Mi-Sport, the same bottle was in miniature design here. Too bad that there is the gel in this small handy bottle nich to buy.
NEGATIVE: no evidence of the contained ingredients. More and more people are alergisch on anything. For this reason alone, the manufacturer should publish the summary.
