For webcam chat, such as Skype, they can be very good use, the screen does not wobble, stutters not, the colors are very natural and the resolution is absolutely great for this price category!
Since the focus is designed to 40cm Distance and more, the picture is really sharp, you as long as 40cm away is (you should anyway;))
Was not disappointed and definitely buy recommendation, if you're looking for a camera for ~ 20. Better to buy the part here, as a more expensive product to buy in stores like Saturn or Media market with less power!
