Review on 🔒 Enhanced Online Security: 9-Pack Webcam Cover Slide for Laptops - Ultra Thin Design, White Ring Indicator When Open, 3M Adhesive, Upgraded Model - Perfect for MacBook and Any Laptop - Black by Nonito Shin

What I like: the red dot that makes it easy to tell if the cover is open or closed. What I don't like: The round hinged lid sometimes detaches from the base and falls off easily. The sleeves I put on my laptops are fine. The cover that I glued to the smartphone after a while (maybe a couple of weeks) detached from the base. I had no idea where it had fallen so I removed the base from the phone (which came off very easily), cleaned the phone thoroughly and put a second case on the phone. Maybe after a week or so the round sliding lid will be gone again. I won't try a third time.
