First, these are SMALL! They don’t take up a lot of your cell phone screen like other camera covers do. Second, unlike a lot of the plastic camera protectors, these have a larger sticking area and not just a ring. In other words, they won’t pop off when you put your phone in your pocket or purse. Because they are small, you need to make sure you align the hole precisely with the camera, but there is no camera blockage. And the magnet slide cover works perfectly! This is the first camera cover for my phone that has actually stayed on and worked!
