The Sota is a good lymph pulser and also a good imflamation/pain reliever as long as the source is not viral/bacterial/parasitic/fungal. I think BG may be on to something as the design is specifically for germ killing, perhaps a smaller scale version of the mighty Papimi machine. I would like to try the 5K to see if it does what it is supposed to do but $$$ is a little tight.
