i'm pretty sure (wouldnt put my house on it, but maybe a bottle of beer) that the silver is used to catalyse the degeneration of the peroxide into water and oxygen.

Hey Lobby,
I would say the same. Maybe helps to stablise the H2O2 at room temperature? Waste of money as far as i am concerned. Silver is expensive but only makes you feel as if you are sanitising better.
If you are near to a dairy ask them if you can buy some of the sanitiser they use. Probably the most effective way (cost included) to sanitise.
Chlorine works just as well but needs "rinsing" for beer.
cheers
