This web cam is a good one, but it does not work with Yahoo IM. I have did all the troubleshoots, but it does not work with it. You can record your video and send it on yahoo IM. However it does work with Windows Live Message... The sounds does echo, but you can go in and adjust the sound. I reccomend using a headset because its easier to use. The built in mic picks up very well and the pic and video quality is better than I expected. This is a good product for its price.
