My impressions of the keyboard are as follows:
-angemessene volume for a mechanical keyboard, not too loud or distracting.
-Pleasant pressure point, very fast response, no double trigger accidentally.
-flexible macro use by the 6 G-keys, each with 3-fold assignment by profiles
-Gaming Mode (off Windows key, etc.) marked with light (as CapsLock, numpad undso), is working properly
Drivers without problems installed (Management with me on the same program as in my G700).
Illumination levels in regulated and switched off, convenient for people like because I need me the light only in some games and at LAN parties or at night and otherwise anyway blind write, so rarely need light. However, it is customizable, not too bright
-also marked with light that G-key profile is turned on (permanently, separate from the rest of the keyboard illumination, but not glaring or disturbing)
Accordingly, I can sum up by saying that I'm really happy with the keyboard and me now nothing better more can imagine ... must, however, as a neutral point to say that you have to get used to the layout only, because it is relatively narrow. For normal-sized hands although this is not a problem, you get used to it fairly quickly. Large hands could depending on the person, however, a problem with getting (but that's what the money-back guarantee (depending on the purchase source).
