The bubbles should be gone in a couple days. If they are still there after four days, and they bother you, then reapply.
Good luck!
I don't believe in screen protectors.. These screens are made very durable, you don't need a shield. My iPad has been through many young childrens hands, if anyone is going to scratch these screens it will be these kids. My screen looks as new when it came out of the box.
Scratch protection should not be your only consideration when thinking about screen protection. If you take your iPad outside you will not be able to see the screen because these films will reflect sunlight and darken the screen.
Only the NuShield DayVue film offers GLARE and SCRATCH protection in one. The film installs WITHOUT BUBBLES or hassles in just a couple of minutes and lasts a long time. At $22 per film it's a bargain.
