Ok, so the item arrived in good shape, well-packaged and ready for application. Instructions or a link to a video would have been nice, but not included. So I just went for it, main screen protector first. I was really disheartened to see that there was a line where the two pieces of backing met and several little bubbles at the bottom after application. HOWEVER... just as described in the listing, after 24 hours (less than, in fact), the marks have all gone! I am impressed! Highly recommended!
