SteelSeries Kana Mouse Review @ XtremeComputing
 

The KANA falls in to the middle category, classified by Steelseries as “the middle child” the KANA fills a void often left in the market for high end business users and casual gamers. Not every office worker needs 7-20 buttons, not every gamer needs buttons everywhere when just a few extra will suffice for the casual gamer, the KANA with 6 buttons and easy to use UI is poised to fill this gap.
