I bought this Logitech QuickCam for Notebook Pro to use with my laptop. I have several Logitech web cams on other pc's but needed something to attach to the top of an LCD. Brilliant camera, but the thing that lets it down is the way it sits on your screen. There is no definite 'clip' for attaching it on, just two small legs and the lens cover to help it balance. Could do with something more like an actual clip to help it stay in place rather than watching it slip sideways or backward. Most amusing through mid-conversation!!
