The C500 webcam by Logitech is a stylish camera in usual good quality of workmanship. The image resolution is very good, but I bought the camera for video telephony at ICQ and since it just does not. I have tried everything, install camera, reinstall ICQ new, but has nothing to download updates used!
Conclusion: This one is from Logitech but stayed elsewhere. I'm totally disappointed because I've just bought the camera for and with my ASUS laptop with integrated camera dei Viedeotelefonie ICQ works perfectly. Would not buy it again, as long this problem has not been solved.
