Works out-of-the-box with Skype 188.8.131.52 under openSUSE 11.2. Very good quality.
The camera has by far the best and most flexible stand I have ever seen on a webcam (I had 5 thus far from Logitech, Creative, etc.). I fits securely on top of a thin laptop screen, a wide old-style CRT and even on top of a 1 inch thick desktop LCD (most webcams I had had problems affixing to the latter). The stand can also be screwed onto a tripod. In addition, the webcam can be turned and tilted for easy positioning.
The webcam's slim round cable splits up at end into USB and a standard 3,5mm audio plug for the integrated microphone. This can be regarded as an advantage or a disadvantage, depending on how well your Linux supports USB audio devices.
I have not found out how to turn on the 6 illuminating LEDs under Linux, zooming, nor how to make use of the button.
The webcam arrived in no-frills bulk packaging: just the webcam in an unlabelled clear plastic bag, nothing else, not even a tag or brand name.
