I'm not a techie, and will now write here no high technical recession ... I am a normal PC user who has bought his first webcam. Did the HD 3000 ordered yesterday and thanks to Prime already get today. I've unpacked, moored at the laptop, plugged in and already we went - without a long install or otherwise. The image is razor sharp, the sound super - I am fully inspirits of this Cam. And the price is also fully ok !! I would recommend it only !!
