the manual is in English illustrated, drawings are included.
I just have not found the squeegee to remove bubbles ... but if it is however well in the box ... in a mini bag I identified initially as an anti sachet moisture found in many package. I'm checking my preview after I jettais nothing but packing.
In this same tiny bag there a mini cleaning cloth and wipe alcohol 70% which I dare not use it because we know nothing of its mode or place of manufacture, I preferred my Special usual product identified from the screen!
In short without raclette, the number of bubbles is almost nonexistent if one follows the instructions so I was pleasantly surprised.
Protection is rigid because of its thickness is therefore little hope which fulfill its role.
For my part, and unlike other comments I read I do not voluntarily testerais efficiency by purposely mauling my phone so I can only assume she does the job in any case it has the physique!
