I also use it on my laptop (MacBook Air), it works well, it's not too heavy and neither is the cable (which is the problem with other cameras). I can recommend it.
I only ever use it with a laptop and it basically works well, it's height-adjustable etc. I'm very happy with it! the only thing that doesn't work is when the chambera is attached and you tilt the screen too far back (when you're sitting close to the laptop) - then the light pulls the screen down with it. But I usually only use it during video calls anyway and put it away briefly in between.
