New to Pulsing - Please Help!

Hi

I've started taking collodial Silver (bought from store and far too expensive) and I've also started drinking foodgrade Hydrogen Peroxide....yuk, but hey, if it's good for me then I'll do it.

I want to buy a blood purifier/CS maker all-in-one and was thinking about the Silver Pulser ZBB5....

Would anyone recommend this one, i would quite like to buy a good quality one rather than a cheap one. But then so many people talk about the cheap ones.

Also i've seen a lot of posts that talk about the 7min zap, 20 min rest, repeat, and so on, then other posts talk about zapping for 2 hours straight. Does the 2 hours of straight zapping refer to the blood purifer and the 7/20 min refer to the magnectic pulser? I'm confussed, can someone please help.

Thank you

Dave
