Intrigued by the previous reviews I bought the G15, and put without problems immediately so that going on.
Create Potty macros, assign shortcuts to convince the user-configurable LCD display and especially the one + off switchable keypad illumination, with two brightness levels.
Tactile, sound and feel of the keys are slightly better than the "normal" Logitech Keyboard, my old Cherry is against a dizzying noisemakers.
I use the G15 primarily for typing, to play less.
Webmasters my 18x3 G-keys functions are of course very accommodating, whether it is the start of the various browsers, graphics programs, editors or office applications.
No Click on Start, Programs, and then scroll, Noo, pressed once to a G-button and the previously there yerknüpfte program or macro is present.
For people who often need to write a lot and, for Chatter, and for all those who want to decorate your desktop with a real eye-catcher.
I give the G15 no longer ago.
