Product use (personal note 3/5):
The +: good quality Film, perfect transparency. Overall good grip. I must change after 1 month (fortunately I have 6 in the delivered batch) but can not tell if the take-off of in my heavy use or quality of the product. See over time with the use of the second film.
The -: Too bad we did not unlike other models:
. screen cleaning cloth to prepare the surface of the phone with the installation of the film (using a tissue moistened lava glass)
. plastic card to avoid the air bubbles (CB compensate but be careful not to press too hard may scratch your new movie!)
. (And especially) on the contour edges of the film to take and apply the film without putting fingers on the film itself (becuase the film may have traces of your fingers ...)
