Hardware good, software mediocre

So of the optics, the G19 once and just looks out top. All modifier keys such as the Media key and the volume wheel work great and without delay. The programming of the G-keys is a breeze with the included program itself for Layen. The display is large enough and bright and the menu navigation is also solved optimally. For people who like to play (such as Call of Duty, etc.), the slide is to enable / disable the Windows key is a blessing; so it may not happen at last that one accidentally comes on the Windows key while playing the game and the game ends.
But now to the small negative part: There are very few apps to extend the use of displays and intensieveren. Those who are pre-installed, are not necessarily more useful (I have a clock in the taskbar on the screen and the media player I can see what song I'm listening to, because I do not need this information on the display). Also, I have until now only one game, which is compatible with the display and gives me additional information.
So is the keyboard with lighting and everything is top, only the compatibility with games and expanding through apps is not too big. But otherwise a strong buy recommendation and app on the D19 range does certainly also something else in the future.
