I'm looking for 2.4Ghz wireless gaming keyboards.
Corsair's 3 keyboards - K63 wireless, K83, and K57 - look great, but I'm wondering how long do they take to wake up from sleep mode. Some wireless keyboards (or mice) ignore first input when they are in the power-saving state, so it is very frustrating. Logitech's G613 solved this issue but unfortunately, I don't like Romer-G switches.
How about these products? Do they wake up instantly? Especially K57 is the first keyboard that Slipstream wireless technology has been applied. Is it something different?
