Nope, not the mythical snake yarn, the latest gaming mouse from Razer that inadvertently broke cover over at the FCC. While it's been official for around a month, Germany's annual gaming convention has offered us our first chance to get to grips with it. Razer has tied itself in a ergonomic knot over the Ouroboros, with most of the mouse's dimensions happily adjustable to suit practically any gamer hand. We get customizing right after the break.
