easy to use. even the trial version version lets me play the video without any logo. works best with yah00, M$N, camfrog and paltalk, I don't use any other messenger so you need to test it yourself. The best thing I like this one is that that it alows me that trial version shows logo after each minute and not all the time. The other software webcam I tried, they all show logo or their trade-mark right away.
