The lack of a numeric keypad and the keyboard’s pleasantly tiny shape are the most striking aspects, but there’s a lot more to it than that. The Pro Gaming Keyboard has Logitech’s Romer-G mechanical switches, which activate at just 1.5 millimeters – 25% shorter than regular switches – and deliver a 25% faster reaction time than the competition. Romer-G switches have also been tested for over 70 million keystrokes, ensuring that they will not fail you when you need them the most.
