What's more apt than getting a gaming mouse from my dota buddies? Though I don't understand the meaning of "2000 dpi laser engine" or "full-speed USB (500 reports/second)" or "maximum accleration of 20G", I thought the label "gaming-grade software" on the box sounds like something I can use for gaming purposes. But I don't understand why a gaming mouse needs 6 buttons.

Thanks for the really beautiful sunset and sunrise in North Cape Jilyn! haha it didn't reach me in time! >.<
