Last but not least as far as buttons go is a small one to the right of the GamePanel controls with a sun as its icon, which switches the G13's backlighting on or off. Though most gaming keypads on the market offer some form of backlighting, none can match Logitech's implementation. Using the supplied software, the G1 to G22 keys, backlight control button and GamePanel can be lit in any colour you like, and made just as bright or dim as you want. The only exception are the M-keys, which are always backlit and only in red.
So far, Logitech's G13 Advanced Gameboard seems to be holding up pretty well. Quite aside from the luxury look and feel, LCD screen and multicoloured backlighting, for those wanting lots of buttons there simply is no other choice. The four directions of the thumb-stick each act as a programmable key and the stick itself can be pressed down, which combined with the two thumb buttons and 22 G-keys gives the G13 29 fully programmable keys as is. Add in the M1 to M3 toggles and this number goes up to a staggering 87 keys for any single game or application.
As usual with Logitech, the software is also rather good, though it could use improvement in some key areas. The basic interface of the 'G-series Key Profiler', which controls everything but the GamePanel, is both attractive and well laid out. Offering a visual representation of the G13 where a click on any of its virtual keys brings up a menu with various options, matching keyboard-keys, scripts or macros to each of them couldn't be simpler.
Unfortunately the same can't be said for the menu bar controlling profiles, which can be a little confusing and feels more haphazard. Also, Logitech offers just a single default profile geared towards FPS games. While the Key Profiler will download custom profiles for many popular games automatically, there are titles it does not recognize. Worst of all, it only allows access to profiles for which you have the actual games installed. As it doesn't offer default profiles for various gaming genres, Logitech should have at least allowed you to get profiles for games you don't own that might have similar control systems to games it doesn't recognize.
