I've been using it for over a year. It turned out that the plastic part that closes the webcam puts a lot of pressure on the screen when it is closed. As a result, my new MacBook broke. The screen flickered on and off. The repair service said the reason was this magnetic shield and he was pressing the screen. Don't buy or you will damage the screen on your MacBook.
