I love this keyboard:
-The Ease of programming macro keys. (An option for me before so it was very intuitive on my cyborg, but this g19 programming is so simple and fast that we would do without more.)
-The Sound setting by dial
-The Overall look.
-L'écran LCD (if somewhat optional, applets for g19 keyboards are rare. I would love an applet for temperature, to control speedfan involved, and a simpler setting pop3 to check his email on the screen)
I do not like:
The backlight is even and too feeble.
The 'key () that are not easily visible to the special characters used by Logitech.
A very good keyboard overall sober and effective game, I do not ask him anymore.
