Review on 🔒 YAYAO Magnetic Privacy Screen Protector - Anti-Spy/Glare Filter for MacBook Pro 15" (Late 2016-2019) by James Holker

Definitely worth buying. It hides the screen effectively and is better than other brands I've tried. I've tried two others (Kensington and some off-label devices) and this one is much more efficient. Turn down the brightness for maximum privacy. But even with a little more brightness, it's still pretty effective. Of course, someone standing behind you with it turned on can see your screen to some degree, but rotating your laptop a bit is quite effective. I like the magnetic mount, it makes it easy to use. Note that sometimes your laptop won't shut down 100%, but usually my laptop can still go to sleep.
