Very fast delivery. Unlike all my other purchases from Amazon this screen does not give me satisfaction. Recovery without problem by Amazon: clear, simple and effective procedures via the Internet. Back prepaid by Amazon in original package by mail. Immediate refund. I therefore take this concern to express my satisfaction with Amazon services. I am satisfied with this screen display. The touch is quite satisfactory for classic controls but not "in the corners" for Windows 8. Furthermore, the copy received, I observed a small random defect touch.
