Summary: In low light it is definitely not HD, but it works really well in low light situations. You can get a decent, recognizable video in a dimly lit room. It isn't HD video unless the room is very bright.
Summary: Maybe you want to at least double the money for a name brand. I've been usingthis for almost a year now also. For the money there is no other that comes close. Buy this one and save your money. It works great with skype / twitch / google - anything i have used it for it is recognized and is truly plug and play.
Summary: It didn't work on my PC, no video. It worked on my work laptop. I wrote a4tech tech support and they said it is not compatible with some USB 3 ports. All of mine are USB 3. I'll have to try a different one.
