I ditched my CS kit maker for the same reason and instead started diluting High PPM ColloidS Silver 10,000 PPM down to as low as 20 PPM.
I can tell you, my pet love it at 20 PPM, but I usuall take 3000 PPM.
I make a lot more with less out of pocket costs and not have to worry about electrodes, how long to run the maker, or if the silver generator fails to work, warranty issues and so on.
