The anti-glare function does work as described. However, it sacrifices the clarity of the screen display and I can't even recognize that my iPad actually has retina display. The screen looks as if it's filled with red, green and blue dots...I'm thinking about replacing the current screen protector with a clear one.---Edited:Now that I've seen what an anti-glare screen protector is like, I realize the clear one is indeed what I need. TechArmor has a great customer service and has kindly provided me with a change to try the clear screen protectors instead of the anti-glare ones. I'm seeing myself as a returning customer. 

Question: How is the product?
Answer: The anti - glare function does work as described
