Query: Save Your Money

I bought this product hoping that it would reduce "glare" - which, to me, means light reflecting off the computer screen. All this product actually does is dim the screen a bit - you can accomplish the same thing for free by just playing with the brightness of your monitor. Worse, the product is highly reflective - it catches the light from overhead and reflects it into your eyes while you are typing... which, to mean, seems like the opposite of what it should do.
