"Pros: Easy to set up, sits on computer monitor with no extra parts needed. Good quality video. Easily adjustable and movable. Many quality adjustment options. Cons: Light doesn't always come up when it is on / working. OBS does not pick it up consistently (may be an OBS problem). If monitor is knocked / desk is shook it can move and/or fall."

Logitech C270
Amazing value entry level webcam. At only $20, this webcam will get your foot in the door and guarantee superb quality for your streams or Youtube videos. This webcam records at 720p, which is a step down from its big brother, the C920, but this is still a great value cam that's impossible to regret spending $20 on.
Microsoft LifeCam Cinema
Not a Logitech cam! While this and the C270 are very comparable, this camera records colors much crisper. That's something the C270 notoriously has problems with. Aside from that, you obviously won't be customizing this webcam with Logitech software, but rather Microsoft software. Some people prefer one over the other. The biggest advantage this lower-end cam has would definitely be the built in microphone.

Logitech C930e
Minor improvements as compared to the C920, but improvements across the board nevertheless. With crisper color and shadow detail, wider field of view and a better encoder, this webcam might be the best value product for streamers period. (It also comes with a nifty lens cap!)

Logitech BRIO
As Logitech's most recent webcam, this is one of the best on the market. Next gen Logitech products have a history of simply being better than the last. This camera has exceeded those expectations. With 4K recording, this webcam is ideal for Youtubers who tend to make full-cam videos, and for Creative directory Twitch streamers.
