I think OP is talking about the _new_ Snowwolf 200W Plus (which goes up to 235W apparently).
I just bought one over the Alien, but therefore have nothing to add about its longevity.
Does TC on all metals, and is quite a handsome device.
I hope I don't regret the purchase, but I have a 1 year warranty on the thing.
Alien has the runs on the board, but everyone seems to hate the old Snowwolf, however, if I remember correctly, Smok was a terrible brand in 2015... in 2016 they really scored some runs. Perhaps the new Snowwolf will have a similar change of reputation?
