The Razer Viper gaming mouse gets man-handled by Gaming Nexus. The small upstart hardware company has gained a rep in gamer circles as being the only mouse you'll ever need to frag with. The review gives the thing a pretty thorough thrashing, putting it up against one of the big boys, Logitech's MX510. The ambidextrous design could be a turn-off for the right-handers out there. But since Razer is the only company to offer lefties a high-end gaming mouse they do have a built-in customer base.
