I've looked through the Korean forums and saw many reviews on this product. While some say it's perfect, some say there are problems. For example, if you happen to leak the liquid adhesive on your speaker or any other buttons, it breaks them. Also it seems that it's very hard to remove the leaks. Even after the success of putting it on, I've seen pictures of it not being glued on perfectly or it lifts. There are comments saying that it's not worth 45 dollars to break the $850 device. But like I said, if you follow the instructions and had no problems attaching it, it seems like a promising screen protector.
