I made sure to follow the guidelines to install it (I watched the video). I successfully installed the first one, and then i realized that the right side is kind of foggy especially when the screen is black but I liked the quality of the product and how it's sticking to the screen but I didn't want to keep that foggy side there. I removed the first glass protector, and I installed the second one and boom, exactly the same same problem. foggy on the right side exactly like the first one. I like this brand and this is our third time buying it but this time it disappointed me.
