In my opinion just another lesser quality mostly ionic silver solution with lots of hype - and pretty pricey per PPM. Though they don't say anything about their particle size, it must be quite large - as their 10 PPM product tested out to have but 1/235th the surface area per given volume as did the Utopia Silver 20 PPM Advanced Colloidal Silver and even less than that when compared to Purest Colloids 20 PPM Mesosilver. (Note: the smaller the particle size the greater the total surface area per given amount of silver).
