Having watched the uploaded video, I can say that the quality when you use something like Skype is probably better than this recording, especially if you're on an HD video call. The recording here is the lowest quality setting. It's important for Skype users to note that only 3 webcams currently support HD calls, and this is one of them.
Just remember that this is a recording and your video-conferencing quality will be dependent upon your Internet connection.
Because of the low lighting in the room you'll also notice the light level fluctuates slightly but that's due to the camera being put through it's paces in a less than optimal environment.
Also, it seems the videos on Amazon can sometimes play a bit pixelated, but the recording is clear so refresh the page if that happens.
