At first, this type of equipment seemed to be dispensable but really ... No, for gamers that require a number of quickly accessible shortcuts, it's a must! The movement via joystick thumb quickly becomes very natural, leaving the other 4 fingers available for walking on the many shortcuts (configurable on the fly, and under three modes profile); and if you really do not get it, the same joystick can be converted to 4 shortcuts, making 7 programmable shortcuts inch reach (if we add the two buttons around the joystick and the touch of the same joystick). The configuration can be long but the profiles are available, they can be transferred via the internal memory of the controller, and logitech drivers for my taste very well thought out, especially if you have multiple devices of Gamer range (g13, and G110 g500 in my case), it's all-in-one and once configured on the application executable, the profile is activated automatically. Finally, the screen can be useful with TS3, I appreciate the integrated clock but I'm not me leaning over it.
In short, despite the price a little high, I do not regret my purchase!
