Mounting easy fit ok ... usability well ,.

The title says it made the most essential.
Pro: The installation was simple. The glass has been adapted fortunately shortly after hanging up independently and without pressure applied to the display without bubbles. The dimensions (Xperia M2) fit perfectly.
Contra :, explains how to install was only available in English. The supplied alcoholic cloth (which should be slightly damp) was completely dried up. The operation will be partially impaired, especially at the edge (letters a, s or pulling down the status messages) often encounter problems. You have to press significantly stronger than without glass.

As a protection in order, for just 7 Euro you can say nothing. However, I have the operation again testen- longer if it does not get better, the glass flying back down.
For now, I wish to make any recommendation to buy.
