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 Brandon Plowden

They are great for the price and come in a pouch to put in your backpack for easy swapping out on equipment if/when one breaks. On a laptop: it hasn't broken or come loose yet, and so on for 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.
