To ensure that no one is watching these Tintelek Webcam Covers work. They are simple to install, just peel the back off and in the open position place it carefully on your laptop, tablet or computer so that the camera lens lines up with the open window. Once I had it in place properly I applied pressure to make sure it stuck good. Then I slid the door closed on the webcam cover. I didn't touch it for 24 hours to make sure it had time to stick really good.
The cover sides open/close easily. This package came with 3 webcam covers. Two were black and one was white. They are made very thin so they didn't get in the way of closing my laptop at all. I did wish the open compartment was a bit larger this would have made it easier to line up and apply to the camera lens. The glass area on my laptop was bigger than the hole on these webcam covers so part of it is stuck around the glass. I think they should have had a larger opening. This being the reason I gave this a four-star review instead of a five-star review.
