Bought as an "emergency" temporary fix to a broken screen for a 3 day turnaround for £14.99
As the unit comes with a frame and glass (plastic?) fitted, it removes the need for faffing about with adhesive so much easier to swap ( took me 20 minutes with the correct tools while eating lunch).
Unit is definatley not OEM/Genuine, as the finish is different - it's smooth plastic rather than rubberised, grippy, and the glass feels lighter. Will have to see how it stands up.
Just remember to move the earpiece, main gasket and mic gasket from your old frame to your new frame (your earpiece may be glued in place)
