The product may be flawed. It doesn't adhere anywhere but the edges so either the curvature is wrong or designed to have a flat gap of air throughout the entire screen. No adhesion bubble appears when installing but there's a ripple of rainbows where it sort of sticks to the screen and creates light distortion which moves around if you press on it and slide over the screen. It's incredibly reflective so it looks like there's just plastic on the screen unlike normal glass screen protectors which feels and looks like there's nothing applied. Also there's a line going across the edge of the screen on either side which I'm guessing is because the adhesive only runs along the edge of the screen protector.
