I finally found the order page on each website, Silver Puppy and SlverGen. The SilverGen looks really complicated and expensive, and though the Silver Puppy looks better from both of those aspects, it still looks complicated. I don't use silver all the time, just when one of us is getting sick or having some other health issue, usually short term. So would making it at home make sense for me? Do you have to keep up with it, do things to it often, or do you just plug it in and leave it alone until you use it up, even if that takes a year?
