With 20 programmable buttons, the G600 is set to put all of your MMO gaming functions at your fingertips. "Twenty buttons might seem like a lot for a mouse, but managing spells, attacks, potions and items can require a hell of a lot more," Destructoid says, pointing out that, for MMOs, "few mice compare." PC World also likes the G600, calling its customization software "a definite win." However PC World also found the mouse's ergonomics a bit challenging, especially given its lack of hardware adjustment options. However, PC World still found it to be one of the "most pleasant and easily customized mice" around, and said, for MMO players, it's "a hard mouse to beat."
