Kensington - MagPro Elite Magnetic Privacy Screen for MacBook 13"- Scratch Resistant, Damage Resistant - Matte

This is a great option for working in an office and keeping your screen secure from unwanted viewers. The only challenge with this is that it has to be pushed up towards the top of the screen to get the magnet to hold; otherwise it doesn't slips down. The laptop can be closed with the screen still on and will sleep but it doesn't allow for a full closure given the slightly thicker edge to the magnetized part. Great overall screen!

works well from the side views, but the behind view is not protected. easy to install, and comes with a sleeve to store the protector in if/when not in use.

Works great. protects screen and privacy recommend this product
