Pretty good glass, almost like the factory one, and the camera looks very good. It also has the special glue on the glass, so you just take it and stick it. Just make sure to clean the area very well before sticking it, and there shouldn't be any traces of the old glue or pieces from the old glass.

Changing it myself saved me money..At the mobile repair shop, they were asking for 60 euros. It requires a little attention and patience during installation. I broke the first lens and managed to put the adhesive tape. On the second attempt, everything went well.
