No need to cut anything.. there are still fingerprints but they don't show nearly like without it. It's hard to notice them unless you look at the right angle in the right lighting.
I used 2 pieces of electrical tape (something sticky but not overly sticky), rolled each piece in a circle and stuck it to the screen so I could use it like handles to apply or remove it until I got it straight and center on the screen. Then just peeled the tape off.
