What is going well:
The backlighting of the keys is very good, adjustable, without much light leakage and not too dazzling (even with glasses)
The touch keyboard is excellent, fairly fine touches (not chicklet), very quiet, very well that dampen the strike with a depth and a very well dosed resistance.
All the keys are flat, except the bottom (ctrl, alt, windows, space, etc ...) which is curved, it is not shocking in terms of design and it helps to have a mark for location hands.
A small flat, the backlight does not see the F1, F2, etc ......, only the part with the orange icon is illuminated.
By cons, 2 more annoying flaws:
1) This keyboard is limited to maximum 2/3 keys simultaneously: PLAYER, flee this keyboard. This is a limitation of marketing techniquo Logitech that did not exist on their old keyboards public and intended solely to sell the G line for the market of gamers.
(Example on BF3: front (z) + run (ctrl) + jump (space) does not work, you have to release z or ctrl for the space key works)
2) If you have a newer PC and you have a dual boot or simply want to access the BIOS on your machine time to time, this keyboard has a fault in the power supply which prevents run before starting the operating system keyboard is not functional until the beginning of Windows loading .......)
This problem occurs on many recent motherboards, Logitech is aware of the problem for some time an article in their FAQ is also dedicated to him but still did not change the firmware of the keyboard and will do so without jammais doubt).
Only solution to use the keyboard when the bios: unplug before turning on the machine and reconnect during the starting phase, in short not at all practical especially for people who have a dual boot Windows XP / Seven, Linux / Windows, etc ..)
(Some motherboard manufacturers however offer a BIOS update to prevent this issue)
In short a good keyboard, but marred by 2 unacceptable defects.
