The keyboard is often the poor relation in the equipment of a PC and that's a shame because it remains the main device entry. So choose carefully and this according to the use we want to make. This keyboard is oriented game with an integrated backlight can be adjusted with 2 levels of intensity or off. This lighting is blue and I find successful. Who says said macro game and there is nothing wrong although 18 keys are programmable. Programming is easy and very straightforward since it is sufficient to press the MR key then select a macro key and the key sequence and end up MR and that's it. Of course you can go through the Wizard software for video games (he should download the Logitech site, no CD). This software scans your PC and installs directly recognized gaming profiles. Of course we can all be programmed same.
Also present are some significant details: such as the joystick button that switches the keyboard in game mode which disables the Windows key, eliminating problems when you select them erreur.Les famous WASD keys are differentiated from the rest of the keys ( gray and blue integrated lighting).
Icing on the cake in the back of the keyboard is a cable management system (slots for winding and decrease the length of the cable). What is it for, well, for example for its gamer helmet that has a longer cord and comes on the keyboard.
Finally typing comfort is with raised keys (there is no mechanical buttons) and a perfect fit with the keyboard risers and non-slip pads. One may regret the small built-in screen or usb hub but that's all and that's normally reserved for more expensive models.
