My personal opinion (basic star deduction):
The film makes it really beautiful AMOLED display of the Galaxy Note to a hideous Gräul. I did not expect. I'll try to describe how the display after applying the foil acts (Matt!):
Like the time a CRT monitor, which has already been in use for hours not demagnetized - totally blurred, ugly.
But this is only my subjective impression!
Thus, I advise rather on a purchase because the display in its colorfulness and sharpness is affected too much.
