Those who showed me the accessories are now to be added to the analog stick of your controller is compatible with both the Xbox 360 gamepad and with those of the PS3, but are fine for many non-official controllers.
There are two versions depending on the improvement of your choice. The first is called Speed Freek, with this addition to the analog have two wings that will allow players reaction times impossible with normal levers, you can do whatever you did before but faster.
The second version is called FPS Freek Prestige and goes to change the size of the analog, making them taller, bigger and more comfortable. This will expand the range of movements and their control that will be more precise, even in smaller ones. Their use is maximized in games in the shooter or driving, where speed and accuracy are critical. Now also on consoles will be able to improve their game to reach better results. Especially in the online, where a gadget like this might make a difference.
