The SilverTron is most definitely worth buying...
(I) came to this site initially to collect info so (I) could sell a "Super Generator" capable of emulating ANY electrolysis unit on the market.
Once here, THREE things occurred.
ONE, I got EVERYTHING I need to create one.
SECOND, Because the info came from predominately ONE man, KEPHRA, I could not ethically take his info and turn it against him.
THIRD, (I) wound up buying a Silvertron Elite myself! And since have ordered a couple of custom lids for my labware.
It's hard to improve on perfection friend.

I COULD use my homebrew equipment and get the same results. But NOT without a lot more wires and monitoring the run MUCH MUCH more. I've never looked back.
IT WORKS and is BUILT EXCELLENTLY.
GREAT GUY, GREAT FORUM.
