Review on Compatible MacBook Computer Smartphone Security by Justin Ott

It's simple. You stick them on and they block the camera. They stick well. I even put one on my phone because if you have 6 of these why not? I was expecting the one on my phone to break or fall off almost immediately because my bag is an incredibly harsh environment, but it's held up for the past 2 months. I've had to put the lid back on the rails a few times, but I'm still impressed.
