This product is fine, though I don't know how much glare it cancels out. Not much I am thinking. And it's REALLY hard to put on properly. I'd say this about pretty much all of these plastic screen protectors, but because it's an iPad screen (big) it's even more difficult to do properly. I went through 2 before finally getting it on right, without dust underneath. Dust is the killer. Try to put it on in a very clean dust free environment. One speck causes a big unremovable bubble, making it unusable.
