I've never been a fan of Logitech keyboards on, it remains fairly standard in form and in substance, notwithstanding that it has the functionality called Gamers with 18 programmable keys, USB audio switch, the possibility plugging his helmet on the keyboard (gadget for me since I use an audio optical helmet, not on the quality of sound via the keyboard jack), the essential retro lighting today and LCD screen displaying additional information, but it is very gadget and is not very useful either.
What is really nice is that the software recovers the Logitech website and allows you to configure and control its keyboard and will issue customization is a champion!
Despite that, I still have a preference for the keyboard of the game Razer which I find much more sober and uncluttered although it does not have all the functionality offered by the G510s, it is much nicer not used in form .
