I have purchased a colloidal Silver generator several years ago and have been very pleased with it. It has helped me with my health, even when the Doctor could not. I have given the colloidal silver to others also when they needed help. My granddaughter recently had pneumonia and it helped her recover quickly. I have also used it when I had pneumonia. I would never be without my generator again! I have purchased the silver bars from this site twice now and they are a good deal and high quality. I trust this site to provide me with the great service and high quality products.
