All I can say is:
You want to know if a $15 2 AA battery THERMOLYSIS unit will provide you with anything other than a way to loose $15 plus shipping? I thought you read the site better than that!
For something this size to have much reliability it would have to be a Galvanic Unit, and even then, it would still have drawbacks.
Come on now, if you insist on home work, do what we have told you to do. Find an Electrolysis Buddy to trade work with. Buy and (both of you) read the "Cannon of Electrolysis Text Books". Find a used professional unit, and get to work.
It is still our advise that you find a good to great electrologist and get your work done safely and quickly.
