Review on 📷 Webcam Cover Slide [6 Pack] - Ultra-Thin Laptop Web Camera Cover - MacBook, Laptop, PC, Computer, iMac, iPad, iPhone Cell Phone Compatible - 0.022in Thick Web Blocker for Privacy and Security by Broderick Shetler

The thing is a little finicky when gluing, requires patience. It's certainly thin and doesn't interfere with the laptop being closed normally. But it's black, on a black display bezel (all 3 of my laptops) and small. I can't tell right away if he's closing the camera or not. You notice that quickly when you turn on the camera, but what worries me more is that it blocks the camera when I'm not using it intentionally. I didn't forget to "close" it? Who knows. If this thing were a different, more noticeable color (red, white, yellow, etc.), it would be a lot easier to tell what position it was in. So I still have the folded business card covering the camera.
