Review on imluckies Metal Webcam Cover Slide 0.023in – Camera Cover for Laptop Computer, MacBook Pro/Air, iMac, iPad, Tablet, iPhone 8/7/6 Plus, Echo Show/Spot – Web Camera Blocker for Privacy Protection – 2 Pack (Black) by Patrick Carlson

So far I like these additions to my MacBook. I use them on my personal and work MacBooks and they seem to be holding up great. Extremely easy to place, subtly thin and the side cover slides effortlessly back and forth without moving on its own. I've only been using them for two weeks so we'll see how long the adhesive lasts but first impressions are 5 stars. I used the sticker method but whenever I had to use the camera for work I would rip off the sticker, ruin it and find a spare sticker to cover the camera when not in use. This is an ingenious solution. Stick on and forget!
