Summary: Works as advertised, with decent video and quality audio. Only possible gripe I would have is this: using it over Skype apparently my voice occasionally fluctuates in volume to the receiving party. I have a friend who has the same webcam and his voice is perfectly fine. Skype's problem? Very possibly but just something to be aware of. Overall, probably still the best webcam/mic with noise cancellation at this price range, plus with logitech name.
Summary: Works great, but it was difficult to mount on my full-sized monitor and a little easier but still unstable on my skinny monitor. Also, it's not flexible since the cord is so short, as to where to mount it. Otherwise, perfect and great value for the price.
Summary: I was a little concerned when running setup because the image looked very grainy, but after setup was better. You need a good light source from the direction of the camera to make it work at its best, but for the price of a take-out meal, you really can't complain. It works!
