Made a batch of Silver using the Sota Silver Pulser. I used the stirring system of my Silver Puppy system so I could compare them. The result is the quality is as good as the Silver Puppy. Seemed to have less contamination also. The only draw back is, to get the PPM you want. You have to check the batch with a Hanna meter and turn it off yourself.

The 20 PPM silver turned slightly yellow after sitting over night. The particle size is so small you can't see any beam with a lazer in the dark. The batteries are a little low though, so I can't be 100% sure.

I'm eyeing this 48 ounce empty pickle jar. The Sota will will fit any size hmmmmmmmmm.
