I held off buying any generator until I fully understood the complexity and marketing mumbo-jumbo. For many months, I liked Steve Barwick's
Silver Edge Generator. But I still held off buying anything.
The subject of Colloidal Silver is enough to drive Dr. Phil CRAZY ! REALLY... I have never seen such a complicated Mumbo Jumbo of Marketing BS.
So bottom line, after 11 months of collecting information, I finally found a generator that was "Love at First Sight". The Silvertron Elite had everything I wanted. Most importantly it was a digital generator that offered total control over over the current in Milliamps between 1 mah and 15 mah in 1 mah steps. Then it saves all settings to make it easy to run production. It will produce 1 gallon as easy as 1 cup. They also offer an optional 1 oz silver bar. While it is more expensive than other generators, it's real cost is chicken feed considering buying Colloidal Silver when spread over many years. I look at the cost per year of ownership and pride of ownership as being more important than the purchase price. It has already paid for itself because I have made 3 gallons of high quality Ionic 20 ppm Silver at 2 mah using a 1 oz silver bar.
