I just got mine, it's great. 1080p30 is currently more than enough for web conferencing, which is what I need it for. Much better quality than the tethering feed that I assume this new Sony tool uses.

So it maxes out at 1080p30, right? That's still good to know, and it's a good point about it being good enough for web conferencing.

The device claims to do 1080p60 Motion-JPEG. I don't know if it actually works and there's no guarantee a similar looking device will be exactly the same. See also [1], their device falsely claimed to be USB3 and only did 1080p30. In practice, none of the tools I use let me specify the frame rate anyway.
