While the keyboard may arrive at a fraction of the cost, ASUS claims that the K5 offers uncompromising performance and durability. We find "Mech-Brane" key switches, with a feel designed to mimic the more expensive mechanical boards on the market without the associated expense, there's also 24-key rollover to ensure all keypresses are registered, 1000Hz polling rate, RGB backlighting and a built-in wrist rest for optimal comfort.
