So its no secret you should cover your webcam when not in use. I had mine covered up with a band aid. It was cost effective, but not very convenient. The price point of these made it an easy purchase. You get three super thin covers that slide open for access (which is way easier than a bandaid or sticker). They are easy to install, although you have to be careful to place it and not cover the flash or camera. The opening is small and worked perfect for my camera, but would not have if it were any larger. Super easy to slide and even though thin, it seems sturdy.
