Video:
So far I have only tested myself the video function and think for discussions ranging from the quality completely.
If one that is already something moves one blurred on the same image, which is probably also due to the small lens and the cheap price.
The video quality is worth 4 stars for me :)
Sound:
The sound I've tested with Skype itself and have already telephoned with friends so
and am quite surprised what this microphone for a good volume!
Noise I have hardly noticed, so really good.
5 stars I give for the sound!
For the money you get a really great webcam!
Quite a buy recommendation, if you do not want to spend much money.
