Excellent webcam, which has excellent image quality for a very small price, good quality / price ratio! The picture is very clear, binding is done rather quickly and recalibration (if you move or if you want to show a document) is also done rather quickly. In low light, the quality is a little worse, while remaining still very honorable to what I've seen, and the webcam is able to swing the images to get a sharper. The fact that there is a built-in microphone is excellent, the sound is good if I believe all my friends with whom I could try. As against the technology to remove static sounds is not at the top in my opinion, many extraneous sounds are still heard, and even the speakers sounds are sometimes too picked up by the microphone. Another positive point, just plug the usb and webcam is immediately recognized and operational, no need for anything else.
A small point less finally compared to the software that provides for me, besides being unnecessary (since automatic recognition), brings nothing extraordinary if we really want to tweak the settings. The attachment can also be a bit risky, I wanted to position the camera above my screen, and I find it is not always very stable.
