I purchased a PDair Screen Protector when I first got my N810. All I have to say is....CRAP. I had heard that the N810 was legible under sunlight before I purchased, so the anti-glare wasn't the first thing I looked for. It's great indoors and obviously in low light, but once it's outside, I have to jack my brightness all the way up and shield it with my hand. Anyway, bad decision. I would only recommend this to my worst enemy.
