I tried putting on one of the screen protectors but it somehow had little flecks of lint of dust or sand or whatever already stuck to the sticky side. So when I put it on my phone, there were little bubble with a fleck of dust/sand/lint whatever in the middle. Also, screen protectors are supposed to come with a little card to kind of squeegee the bubbles out. They are supposed to be hard like a credit card. The one that came with this product was so flimsy, it was useless. I just attempted to use my hands to squish the bubbles out. I threw away the first one because of the little flecks and tried the second one. But of course, it also had little flecks on it, causing bubbles. I tried getting the flecks off myself but I just made it worse. So they both got thrown in the trash. At least I didn't lose too much money.
