Films well, but "fit" to

According to Product Description - - "Pass and contours" cut sheets at precisely cut Here are.

I am very much in the mountains and on uneven ground, so I foliere years my equipment (DSLR, GPS units, cell phones). Are on average - depending on the device - the slides to change approximately every 1-2 years - in short: I have enough practice, a film of dust, bubbles and especially to install accurately.

This slide set but the despair was great.
Even if the film was accurately applied directly on the edge of the speaker from the S3, it did not fit at the other end by a hair - the result (!): The film closed around the button not on, very unpleasant.

In the first two films, I still went out of a tolerance limit that has been exceeded. But the third film had the same problem!
So I tried the other "direction" to attach the film, saying: First create the button, then the direction of speakers / rear camera.

It was here the same picture: Though the film was already created directly on the button - without a gap! - It did not fit at the other end - same result: the film was on the speaker "to" closed and thus not really from.

After 5 "sacrificed" films, I decided at the 6th film easily with scissors to cut off the lower part (the button) - because the film is to protect the screen and it does well when a piece missing from the button.

Since the foil with scissors super cut left without leaving ugly residual, "saves" the rating to 4 stars.

Final score:
5 stars for the quality, price and delivery (10 films)
3 stars for not matching foil
+1 Star "Bonus" that the film can easily trim with scissors, if there is a need

PS: Maybe it's my S3 and there are minimal deviations per unit with the masses. But why must know as "extreme" precisely tailored the film? A few "micro millimeter" less would save a lot of trouble and frustration - other manufacturers make the too!
