BenchmarkReviews.com: Taiwan-based Genius may not be a well known brand when compared with other established companies such as Steelseries and Razer, but they have been around for a long time. They were credited for shipping the first mouse with a scroll-wheel, and currently manufacture products for other brand-name companies. The GX Gaming series is their first stab at entering the gaming peripherals market under their own brand. Benchmark Reviews has on its hands the Genius DeathTaker MMO/RTS gaming mouse. We will be testing this premium 9-button, weight-adjustable gaming mouse to see whether this late-comer can take the spotlight.
