Greetings, friend!

I'm so happy to hear that you are aware of the benefits of colloidal silver! :D

FYI, "them" is me... I received your inquiry and responded to it via email. Please do let me know if you have any other questions at all! The rods are good for at least 100 to 150 10ppm batches of very high quality colloidal silver, and they are very easily replaced.

One of these days I hope to tell the whole story of how this machine was developed, and how we produce it. :)

Thank you for your interest, and for stopping by my blog. <3
