I chose the VX-700 due to its price and shape. Its very small and sleek. You can get cheaper VGA webcams but none that look as good as this. Play was the cheapest retailer i could find, after delivery cost.
The webcam has no software its plug and play, installed in 10 seconds, (I'm on vista) and works with both Skype and Windows Live Messenger.
Very pleased with the look, price, build quality, and features on the camera. It comes with monophone headset also.
4 stars rather than 5 due to the fact that you can get better cameras, with better quality picture. I dont think you can beat the looks and spec for this price though.
No flash, but adapts to changes in light well. Not used in dim lighting yet.
Other very minor problem is the fitting to the monitor. It doesnt clamp, it simply rests on top of my flatscreen. Which isnt a problem, as it has thick rubberry pads to stop it sliding, but you can literally just lift it off. May become a problem if the usb cable needs to be stretched or goes in an unusual direction from the top of your monitor.
Other than that, brilliant buy. Highly recommended.
