Honestly it was so easy to get it perfect it's almost fool proof as crazy as that sounds. This protector is some what firm, similar to an iloome glass protector the super thin ones.
That means that it's already shaped to the phone. I peel the film off from below to ensure no dust hits it and placed it right on the screen slowly matching up the bottom button since you can see how precise the cut out is, from there I lined up the front camera cutout and just dropped it down and pressed in the middle as you would with glass.
Since this is not glass nor pure pet film but some other firmer substance rubbing out excess air was rather easy.
Once all the visible bubbles were out I carefully peeled the top layer off to expose the crystal side.
All in all it was easier than glass since it just drops into the way it needs to fit.
Cost is about $25.00 at AT&T but I get discounts due to my corporate coverage from work which is about 40% off accessories
