Useless without instructions

Without the guidance of the wheel change can not be done. The videos on the net are not compatible with this set.
The tool is (a star) for single use hintreichend - after that you can dispose of it, because the plastic is too soft.

The main problem remains. What is one such application and assemble? The adhesive film Apply full surface will not do.
Yes and how rum at all?
If you remove all the cut-outs of the film remains a minimal adhesive edge on edge of the display and the keys left. The so-mounted disc does not work then as a touch screen and falls out.
For other offers a transparent Gelkleber is included.
The disc otherwise would fit exactly.

In my opinion, stay away.
