After struggling with my built in webcam in my laptop, I purchased this and I have not been disappointed.
Excellent picture quality, the mic is better than my headset, no set up required, and it's very reasonably priced.
The clamp is well made and very secure, no concerns about the webcam falling off from wherever I place it.
Compared to the built in webcam I have, it's like night and day. Or more accurately, it's like day all the time as low-light is no longer a problem!
