Ranked in these QuestionsQuestion Ranking
Pro Solid video
While not up to par with a dedicated camcorder, it provides exceptional quality for a webcam. It can manage 1080p video at 29fps while maintaining focus and light balancing.
Pro Flexible positioning
The mount is very adaptable to nearly every situation, whether it's standing on a desk or clipped to a monitor or laptop screen. The rear hinge allows for it to better grip curved surfaces (as opposed to having a flat grip point), and it also can tilt vertically ensuring you are centered in the frame.
There is also a standard threaded tripod attachment point, so you can stand it up with virtually any tripod.
Pro Great audio quality
The stereo mic setup allows the C920 to suppress unwanted background noise while providing very good audio quality.
Pro Controls to provide the best image
There are plenty of adjustable controls available, from amusing effects such as filters and video masks to digital pan/tilt/zoom, auto/manual focus, and follow my face. No matter the lighting, distance, or angle, the C920 will make the most of any situation.
Con USB cable is attached
The USB cable can't be removed - its permanently attached to the rear of the cam. This means that if something happens to the cable (pets or other accidents) you will have to buy a whole new cam instead of just a new cable.
The cable is 6ft, sufficiently long for just about any regular use, however for some situations it may not be long enough. For others, the 6ft cable will be too long, and will be left in a coil. With a replaceable cable, you could swap it out with a better fitting cable for your desk.
Con Slight lack of detail
The bit rate is lower than other webcams (average of 3300kbps for 720p and 4100kps for 1080p), which limits the detail of the video.
