Seeking an efficient keyboard after much research I came across the G510. First design impressed me and other friends and colleagues who have already tested the same keyboard advised me. At first the slightly smaller keys than other keyboards "non gamer" that I had previously used means of had a little "confused" but he has a few hours is enough to get my marks and fully appreciate my new keyboard. The keys are quite quiet and the excellent response, about the possibility of very advanced customization, so that after a month of use I have not had time to shop around. Very popular customizable backlighting and the ability to control the audio and multimedia from my keyboard, which regularly allows me to mute a quick and easy gesture during a call on mobile. Also very practical LCD screen (which is activated when the keyboard control software installed and running) to monitor the development of a game, being music or even that the information that the keyboard can provide (rss feeds for information, date / time profile used, etc.) I have not yet made the rounds of all the functions that give this keyboard an excellent quality / price ratio (for under 100 gamer keyboard with integrated sound card, backlight, and programmable keys) but the weeks ahead and more I am convinced to have chosen well, therefore, I recommend!
