Kit supplied poor quality: the separation tools are functional, but the screwdrivers are not suitable: I draw your attention also to this point, YOU HAVE THE SCREWDRIVER nokia lumia for, try to take the screws with the screwdriver provided will only screw up the thread, with well over expenses to buy a suitable screwdriver . Otherwise correct quality product, but installation can be rough because the glass is supplied without chassis: the chassis is risk of damaging by dismantling the previous screen, because of the powerful glue. But the touch remains effective, it is not a product certified by Nokia.
