It looks like a poor quality product. I've installed screen protectors with no problems. The attached card is not enough to remove air bubbles (see attached photo). The comments here indicate that this is a product that appears to be successful. The manufacturer needs a better product, better instillation tools, or better instructions (yes, I followed the instructions as recommended). Too bad it's a bad product. I look at screens over 6 hours a day and could use a screen protector to reduce glare.
