I really like this product. It is super slim and sticks right on to my laptop (macbook pro). The slide is easy to use and stays in place. I decided to give one to a friend of mine who uses a posted-note to cover her webcam, and she LOVES it. This product is really slim and minimal, and I can reccomend it enough.
Love this for my girls laptop. Going to place it on all our devices. Tablets and phones included. Another protected in this age of lack of privacy.
These are really small, but I think that's a plus. On my black computer you can't even tell it's there. It's like it's part of the computer. These were easy to install. Once installed they stay on and they slide back and forth pretty smoothly. Take that NSA! :-)
