I would not go so far as to call other products necessarily fakes, but it is a bit misleading in most instances when what is mostly ionic silver is referred to as colloidal silver. Having researched colloidal and ionic silver fairly extensively and having a good friend whose company makes one of the two best true colloidal silver products in the world as far as I know, I do prefer solutions that are predominantly colloidal silver, but that is not to say that there are not good mostly ionic silver products out there or that you cannot make your own mostly ionic silver at home that will get the job done most of the time,
The site you refer to is that of the company which makes Mesosilver, a true colloidal silver which is one of the two best to be found. The other product which I consider in the top two is Advanced Colloidal Silver, which is made by my friends' company Utopia Silver Supplements, They also happen to be a CureZone sponsor.
I don't think you can go wrong with either company's product. If you want to save some money. make your own mostly ionic silver at home with a good quality machine and that should be fine for most uses and get yourself some of the top quality commercial products in case you need it for something really tough.
If you are going to buy Colloidal Silver, DQ's friend at Utopia would be a good choice.
Not only good product, but the Government attacked him a few years ago, and he and his lawyers sent them packing.
Worth supporting somebody like that.
I would wager that for every person who says they have had better results from homemade and cheaper products than mesosilver you would find 100 who say just the opposite. I have very, very seldom seen people contend that they have better results with products other than Advanced Colloidal Silver and Mesosilver (the two top rated true colloidal silver products), whereas I have seen scores and scores say that one of the two top products gave them the best results.
I realize that it is hard to wade through all the marketing hype and so-called silver experts - especially with so many of the products claiming some kind of unique superiority. Interestingly, Advanced Colloidal Silver makes no such claims anywhere on their site or in their literature. They have let their product stand on its own merits and results.
As I think I noted earlier, homemade mostly ionic silver should do you just fine for most purposes and the Silver Puppy is one of the better units out there in its price range. For the best of both worlds, get yourself some top quality commercial product for extreme situations and make your own solution for pennies for general use.
