The webcam records 720p video at 30 frames a second with a built in microphone. It was usb plug and play (no software required) and works with Linux.
The webcam was actually quite small, about the size of a usb stick. I put it on top of the monitor and plugged it in to the usb port. The video with Screencastify worked right off the bat, but I had no luck with the mic. This may have been because innitially I had another mic plugged in. However, after a restart I was able to pick up the microphone with no problem.
While one could certainly complain the video and audio quality could be better, I find it acceptable especially considering the $20 price tag.
