Made it my beefiest/fastest/upgradiest production pod on my second playthrough after having serious deficiencies on my first playthrough.
Then I had to expand it. And expand it. And build a whole 'nother *additional* separate copper smelting/coil production pod after discovering that all that was still not enough.
AND IT'S STILL NOT ENOUGH COPPER COIL!?!?

Warning for new players: Once you get to building circuit cards you are gonna need a buttload of copper coil.
