I got a Creative Labs Live! Cam Notebook Pro. I was amazed by how terrible it was and I returned it.
The camera can't handle high light (like outdoors or bright indoor light) and it can't handle low light (like just light from the screen). It also has far too little dynamic range, so either the image has to be too dark or the bright parts have to wash out. The automatic exposure and white balance ends up with wildly different and ridiculous settings on different occasions for no apparent reason whatsoever. The video displays a lot of blocky artifacts, as if it's highly compressed, probably because despite mentioning USB 2 it is not a high speed device. It was able to get a good image sometimes, like when there's a stationary scene with uniform subdued lighting, but performance is generally unacceptable.
My favourite thing about the cam was its impressively small size. I also liked VideoFX although it had incompatibility issues and the effects where I'm supposed to appear in front of a different background didn't work.
Overall, this webcam is so horrible that it's not even worth it when steeply discounted, and it seriously hurts my perception of the Creative Labs brand.
