With its gaming centric software and advanced features, Cooler Master’s first attempt at creating a true gaming mouse - the Cooler Master Storm Sentinel Advance - was almost a complete success. The only critical area it fell flat in was its reliance on the Philips Twin Eye sensor, a failure prone unit that featured less than optimal tracking performance. The newer second generation Storm Sentinel Z3R0 G hopes to correct any perceived limitations of the Sentinel line without removing what made the original unique.
