Gi - Since 1987, Taiwan-based A4TECH has become an international leader in computer peripheral innovation and value. The company prides itself in creating new technology and offering the best possible experience to their customers. A4TECH creates keyboards, mice, headsets, cameras and the like. Their latest line, Bloody, targets the hardcore PC gaming crowd with unique features, bold designs and a price point that is hard to match. The Bloody Multi-Core Gun3 Gaming Mouse V5 sits pretty in the middle of their product line and brings more to the table than some gaming mice that cost twice as much.
