Great mod overall. Wattage and TC modes both worked well with my SS builds.
Ergonomics are not a con to me as i knew what i was getting. But other reviews/ers commenting on the feel of it are not to be taken lightly. The edges quite sharp and can be uncomfortable for some. I don't mind as this is more of a statement mod that sits on my desk throughout the day.
With that said, it feels very solid and well built. Paint job is clean, buttons have no rattle and a short travel time.
