This is the first time I have bought a webcam, which I wanted to use to try making video calls using my laptop. I didn't want to buy the cheapest camera but didn't want to invest too much either since I'm learning how to do this stuff; so this midrange camera seemed like a good choice.
The camera is very handy and I think the image quality is good. It is tiny (about 3cm by 6cm) and comes with a small pouch so it is protected when you pack it away with your other laptop stuff. The camera has a manual focusing ring which you have to turn so the image is nice and sharp - this worked well. (The clip is good for a laptop screen but I think it would be a bit too narrow for a flat desktop monitor, for which I would recommend the Logitech QuickCam Communicate STX which we use on our home desktop PC.)
I took the precaution of ignoring the supplied CD and instead downloading the latest driver from the Logitech website. Driver download and installation was straightforward. I setup the camera using the Logitech software first (to check the camera and microphone, which worked fine), and then I downloaded Skype, set up a new account and started it up. I then made my first call and started the video. It all worked like a dream without any special intervention required. Image quality at both ends was good.
If, like me, you want to try a pretty good quality webcam without spending the earth, and you have a laptop, then I would recommend this one.
