The Roccat Isku funktiniort with the known rubber dome technology, which means that you have to press the buttons all the way, so they react. For me it was nothing, because you have to torment his little finger, especially in FPS games where you sprints with Shift. Maybe it was just in my model so, but the button sometimes does not respond even when she was very depressed. I recommend you rather the Roccat Ryo MK. Great mechanical keyboard, where the keys respond when they are pure 3mm pressed what einafch perfect. Available at an affordable price for all who do not need Tastenbeleuchtuing.
