Bests & Worsts Reviews from Amazon

I have been searching for a webcam. One that actually works. On the advice of a friend I upgraded, admittedly not to the same one she has, but still the same brand. Twice the money I had been spending, in the hope that I would at last find something good. Well guess what... It arrived today. I have tried to get this to work. No joy. The computer doesn't recognise it, it simply doesn't show up. I searched in different ways to try and locate it (with it plugged into differing USB ports), all with no result. It is simply invisible. So I watch some instructional videos on YouTube which tell me I must go to the Logitech website and download drivers for this camera (Why?). I go to the Logitech website. I look at manuals and instructions. very little in English, mostly in Chinese, totally unintelligible to me. .... How about just type in Logitech webcam drivers? Let's try that. So I go. And I look. I cannot find drivers for the C920x. There are drivers for C920 and C920s, but not for this one. I know, I thought, we'll just get the drivers for the C920 and go from there. Round and round the houses on the Logitech website. The only option it will give me is to download GHub, which is basically for gaming as far as I can tell. Anyway, I download it. It wants me to do all sorts of things like register (which will include name, email etc), and to allow them access to my computer and share my data with them, and to share my gaming experiences with others, online. The thing won't let me proceed unless I agree. But I don't want to agree. I just want a camera such that when I plug it in it just works. I don't want to faff about registering and "Sharing" anything that has absolutely nothing to do with them nor anybody else. So.... This thing is just another expensive paperweight. It's packed, sealed, and is going straight back where it came from tomorrow (well, today than 11th). Chinese crap. So disappointing.
