I purchased this product on sale hoping that it will be a glass screen protector that would cover almost the entire front of the iPhone 7 Plus, but I was disappointed. On the item page, there is a IMPORTANT MESSAGE NOTICE claiming that this Screen Protector is SLIGHTLY smaller than the actual screen, but this screen protector seems much smaller than my notion, and understanding of SLIGHTLY. As many already know, this screen protector leaves a good amount of the front screen exposed to unwanted damages, dust, and etc. The width (side to side) of the screen protector measures about 2 11/16 Inches, which ends up only covering the touch screen part of the iPhone, and maybe a little less like with my screen protector. The length (top to bottom) measures about 5 13/16 Inches, covering the front panel from the sensor above the earpiece to around the level of the bottom part of the Touch ID button. There is a opening, not fully encircling the Touch ID. The installation process is not that difficult (even for beginners, and novices), but it did get some air bubbles, and dust, thus had to reapply, and realign the screen protector, which resulted with a few bubbles, and no longer sticking parts. The product (after having used it for several days) is great. The glass is smooth, and clear, and works well with 3D Touch (I am a new user of an iOS device w/3D Touch, so still learning, and not sure if it responds any different without the screen protector). I will be returning this for a refund, and try out some other "EDGE TO EDGE" Tempered Glass Screen Protector here on AMAZON, which I was originally intending to buy.
