So far I've found that bubbles tend to go away after a couple days. I had four smallish ones when I first put it on and three of them cleared up. But when the fourth one still lingered I took a closer looks and that's when I noticed there was a speck underneath
I actually ruined the first protector in the pack because I got confused which was the protector and which was the backing. When I realized my mistake, I had already put the protector down on the carpet and promptly discovered that I need to vacuum
I'm curious how the anti-glare protector works out. I went for the clear one because I didn't want anything to impact the visual quality of the screen, particularly when reading. So far I haven't been bothered by any reflections, but I haven't tried to use the Nook Color yet where it might be more of a problem than my dimly-lit apartment.
