The race crosses and square buttons is low, suddenly the precise dosage is relatively difficult, which lost all the appeal of this controller. After pressing the buttons 50% of their running, you have reached the maximum acceleration or braking.
In addition, the "flying" just has a "notch" to maintain it. So sometimes it escapes you.
The joystick is also a little "cheap", it is by far not at the Sony Dualshock (poorly fitted buttons that move in their slots, ditto for the triggers, too soft springs, average ergonomics)
In conclusion, this controller is a useless gadget that will not improve your times, on the contrary. Move along.
The poor quality of the product does not affect the performance of Amazon and its partner vendors, fast delivery and the product was properly packed.
PS: test carried out under GT6 with vehicles of different powers, for several hours, so be sure to have well in hand lever.
