They are more prone to finger smudges than the bare glass surface, but still not a big deal since they wipe off pretty easily

Since they are a clear protector and not a matte protector they are going to show finger smudges, etc

Note: Since this is a PET Film protector, it will leave finger smudges, but I can deal with that easily.

Finger smudges are much worse on film than on the unprotected glass screen, but if it saves the screen from damage I guess it is worth it.

It also show finger smudges and oil incredibly easily, much more

the upper corner broke as I was carefully putting it on

However I've got only average dexterity and with the inevitable amount of fumbling I managed to trap a bunch of bubbles and the suggested solution to try to scrooch them out with the edge of a credit card was only marginally successful.

this didn't work as I liked the quality.
