Mouse and game controller mode is very useful. This can be easily adjusted down by the controller via a slider.
So you can even if you take the menu or from a game out must control everything easily with the controller.
Unfortunately, not all keys can be used in mouse mode.
In addition, a third mode of phones available, but the controller is only recognized by Android.
If the controller is then (unfortunately yes from time to time quite a chore with reinstallation) first connected, not only convince the two modes, but also the reaction speed. Although I never normally eighth particularly on the reaction rate, but I've yet initially worried whether a Bluetooth controller unless suitable really for PC games.
Unfortunately, he did not use for GTA 4 - but what is the game, not the controller.
Otherwise, however, make both FPS and racing games really fun, and the controller and the connection to the PC can be easily.
Conclusion: If you do not mind, from time to fight with reconnection of the controller (which is certainly on USB not have) and you do not just want to play GTA 4 so (before well-read best in each game, whether standard controller can be used ) I can only recommend it!
