Review on Protect Your Privacy With Sunshot'S 0.7Mm Thin Webcam Cover - Magnetic Slider For All Devices (5-Pack, Black) by Vaibhav Karger

It's very slim. A little difficult to open/close because there's no nub. It just barely fits over my macbook camera without covering the green activity light next to it. So far the adhesive is great (my previous cover kept sliding down the screen). Just a little pricey for what it is. Also, when my wife put one on her iphone front camera and when the cover is closed the camera seems to be affected by the slide magnets (not black screen but a blurry white one). Also, the sliding shutter is only held in place by magnet. So you have to be careful not to knock it out/off when using it on a phone in your pocket.
