Yeah the ease of use was the big selling point for me - but I also like that it always produces a clear batch (maybe something to the constant voltage sensors).
I've gone to the medium setting lately and like it much more for internal use. On the high setting it got too metallic feeling and tasting - though I admit to taking much more at a time now that I'm not paying $20 for 8 ounces.
Still the middle setting is just as effective and easier to tolerate. I guess all those companies making the 10 ppm ionic silver figured that out already. But it's nice having the higher setting for external/disinfecting/cleaning etc.
Was wondering - do you know if it's possible to use the silver strips from other manufacturers with an even higher purity rating (if it exists)? Have you tried?
