I think the commercial Colloidal Silver and the CS made with a generator are equal. I still have a gallon of Mesosilver so I don't need a generator yet.
If I were going to buy a generator, I would prefer the versatility of the manual timer product called Silver Edge. You can make a quart or a gallon, and it has a built in polarity reversal to protect the silver electrodes and a water bubbler used to stir the water. Details & links to the Silver Edge are in my research file, above.
Please do keep me informed of your progress. I would like to include your story in the testimonials.
