Used webcam cover on phone and computer, the adhesive works well but the item itself is bad

These work really well but you do have to be careful as the adhesive isn't the best and it will pop off pretty easy.

Bought this for my MacBook Pro and iMac, work seamlessly, easy to install, just need to put in correction location for the camera

These webcam covers work well on laptops, but we found that there are certain webcams, as on flat screen monitors, that are too large - would need to order a larger size cover for those

These work well on my computer, completely blocking out all light
