Review on Protect Your Privacy With Sunshot Webcam Covers For Laptops, Smartphones, And Tablets - 3 Pack Of Smooth Sliding Anti-Monitoring Camera Covers by Alex Maynard

These are perfect and discrete for covering laptop cameras. The oval outer edge sticks on with an adhesive, and the center slider is magnetic. The slider slides easily, but it doesn't seem like it's going to fall off (mine has never fallen off). It's incredibly thin and hides very well against the black of the laptop. You can barely even notice it. You can only see it in my photo because I used the flash and was a few inches away from the screen. The other pic you cannot see it without a flash. Great purchase and great piece of mind!
