The product works very well with Windows 8.1 x64, before connecting the device, install this driver on the CD. Now we come to the product itself: the product well finished alder quality, it does not look like the photo, but it is not very important. Small problem in the driver: when connecting a PS2 controller, by visiting the Vibration tab, configuration closes and indicates that Windows has crashed, it is not important in the sense that the vibration function normally This adapter is compatible with the same Guitar Hero controllers (everything works except the handful of vibrato that will surely used with JoyToKey).
At the delivery, I ordered on Thursday night, and I received it on Saturday morning so quite fast, well protected shipment, so no complaints on the quality of the seller.
