A superb soldering iron, small flaw, an internal grid melted (hole in the center) from the first use. From outside you can not see. I do not know what it is for, it does not use gene. Maybe I waited too long to light the flame and worries caused this?
Good to share ca I do not regret. The hand is fantastic engage the "lighter" serves as a foot, the boot is practical, we breakdowns for common uses ... Satisfied. :)
