This screen protector is by far the best I have every used. It come with an easy alignment tool which fits over the device. Easy to install and leaves no bubbles. Fits perfectly and feels as if you barely placed anything on the screen. Comes with a wet and dry wipe and a microfiber cloth, as well as a dust remover. This allows you to get the phone spotless before installation. If anything, you can tell its a glass screen protector, but its ever so slight. Definitely worth the purchase. I have an otterbox case on the phone and no issues at all. It is very durable. I've dropped my phone multiple times and the glass protector has only lightly chipped in the corners. I had one fracture across the screen, but it was subtle. I just bought a replacement for the aesthetic and am so pleased my device screen was perfect. It is affordable and has great quality, especially for the price.
