Review on 📸 Premium Ultra Thin Webcam Cover (6 Pack) for Laptop, Desktop PC, Macbook Pro, iMac, Mac Mini, Smartphone - Protect Your Privacy and Security Against Cam Hacks with Strong Adhesive by Johnny Burns

They offer excellent value for money and come in a case that can be stowed in your backpack for easy replacement of a broken unit. On a laptop: It hasn't broken or come loose yet, and it's been about a month. It's also thin enough that the laptop can be completely closed. I didn't believe the other reviewers at first, but that's not a problem, believe me. On the phone: The sticky part stays, but the slider lasted less than a week on me. Sure, I've been pretty active with my phone in my pocket, but still, they're not exactly durable. But they are cheap. Maybe buy a new pack every month. Nothing is perfect.
