I have the glass for a little over a month ago on my Galaxy Alpha. At the beginning it was very used to that actually protruding Home button is suddenly something inside. As expected, however, you get used again quickly. Optical glass is super! The edge on both sides is very small and is hardly noticeable. By the thickness of the glasses completes quasi with the aluminum edge of the Galaxy Alpha. One notices immediately that you have glass attached and no plastic wrap, because the screen is brilliant clear and sharp. We have glass for tablet and my husband ordered the phone, because we are so confident! The application was super-simple - what I am already annoyed around with thin plastic film! - And there was no inclusions. There are also great for applying accessories, such as a part that sticks and allow trapped parts "pick" can. The re-ablation and -auftragen at inclusions is very simple.
Now a BUT that explains the two missing stars. Yesterday I noticed the phone - admittedly not for the first time - back down and it splintered glass on one corner from. Of tempered glass I would have expected more resistance. Of course, one can say that at least only the glass protection is chipped and not the actual displays ... so it has already served its purpose.
