Unlike last year’s Steel Series World of Warcraft Gaming Mouse, the Razer Naga doesn’t come with the full Blizzard licensing. If that matters to you you’re a fool. And also unlike said Steel Series mouse, the buttons here don’t stick like an old Sega Genesis controller after using it for a few hours. It works, out of the box, with both Windows (tested on Windows 7) and Mac OS X (tested on Snow Leopard). Thank you, Razer!
