Details:
She is very well finished, with sides and a rubber underneath to ensure good decision. His form has nothing extraordinary precisely because highly ergonomic and therefore proportions and curves correspond to a PS3 "classic" model that have adopted many current pad.
Note that in terms of form, some prefer "absolutely" that of the Xbox 360 pad, as this F710 is closer to that of the PS3, if you plan to offer it would be wise to check before. But if it is for just you and a xbox 360 (like me), exceeded the brake used (as in all), it proves very pleasant and we adopt it quickly.
So good grip, enough light directly recognized by Windows and MacOS, directly recognized in games as well, even those known to be a bit reluctant (NBA2K11). Very responsive and no latency brand.
On the site is a logitech software to configure on the fly depending on the desired game.
This is a vibrating controller and it comes with 2 long Duracell batteries. But better predict rechargeable batteries. It is more convenient.
Note, however, that like all Logitech unifying Series devices, if only one away from the receiver (~ 3m ...) we must have a clear line of contact, ie no obstacles to ensure good reception. But if one is to his office, ie within ~ 1.5 m from the receiver, the receiver connected behind the tower under the desk did his job without a fight.
Finally, well-finished handle, ergonomic and light, very responsive, handy with its discrete receiver and recognized without problem.
Perfect? ... I have already told you at the start! ; O)
