Cannot Focus
BAD. All the review sites say it's best. I bought it. It has problem focusing correctly for anything within a forearm length. It can focus correctly if something is really close, like 5cm, but when you bring somethnig close, such as a keyboard, within 50 cm but not as close as 5cm, it tries to auto focus but its final choice is blurry. Lots 1 ⭐ review have similar complaints. Also, the other model C922x, isn't better.
here's a video made with the Logitech C920 Webcam.
you can see, the video is blurry.
That keyboard is Ultimate Hacking Keyboard
Right now (2018-12-19), am not sure what other webcam to get.

if you goto amazon Buy at amazon you see people have video review of it, in comparison to the logitech. This nameless one from china, does good, while the logitech one, cannot focus.
also, the logitech was $20 more expensive just a few months ago.
also, if you search reviews, many sites says the logitech C920 is the best. These days, its hard to find proper reviews. All's clickbait copycat sites fried up by Facebook twittec etc.
by the way, the logitech C922x have the same focus problem.
i've also read reviews of other expensive logitech ones. This one logitech brio webcam for $200. it'scrap.
So, never buy logitech's webcam.
however, for gaming keyboards and mouse, i trust logitech, they got the best, and best non-instrusive and great software.
