The weight of the mouse is slightly heavier than the Razer DeathAdder. Along with many mice these days, the weight isn't adjustable without your own modifications. The weight really seems to be what makes it smooth and since you really don't have to "force" the mouse around, it's not really an issue. Overall, I liked how this mouse's design supported more of the hand with the individual finger rests. Perhaps it's not perfect for my hand, but I plan on using it for a while, as I've gotten too used to how well it moves about without getting caught up.
