Acquaintance with this keyboard happened during the Modern Warfare (the first part). For use in shooters, it's great. Attempts to play on ordinary keyboards with a staggered arrangement of keys leave an indelibly sad impression. Also, this keyboard proved to be exceptionally good in battles when playing Age of Conan (MMORPG with no target system) due to the grouping of number keys in two rows, this makes it possible to use all the abilities without having to be distracted from the monitor and losing the ability to "dance non-stop" . The keyboards are quite tenacious, the second such keyboard lives for the second year. The first keyboard, despite the age of 6+ years and the huge "mileage", is still alive (replaced for cosmetic reasons and because of the "need" to have the same one at work :) ). Due to the active "work", over time, the WASD keys begin to sit loosely in it (they begin to hang out like sticks on a gamepad), which only affects the aesthetics, but does not affect the operation of the device. I am considering buying a third such keyboard for the future, since all good things can come to an end, and this keyboard can be discontinued.
