Yes, it does work somewhat: 0.25Ohms of 28guage Ni200 works but, it sure doesn't get very hot. It's a new device AND the board is broken. Now we have to start the process ... repackage, re-mail, return, refund or replace! Anyhow, my question is, will it work with the OCC nickel replacement heads for the Kanger Subtank. I've tried them but, with a fritzy board, I can't tell. Anyone? Thanks.
