Where to start. First of all, the manual CLAIMS that it supports 1080p/60fps, and in OBS it shows that it goes at 60fps at 1080p, but the image is still 30fps (720p and below have 60fps). Additionally, it has quite a bit of input delay, for example on the switch, so I wouldn't recommend it for gaming.

I gave it 2 stars instead of 1 because at least it does its job for simple video I suppose. Also, one could use an HDMI splitter to play on one screen and record on the other. Otherwise, you can't do anything with the input delay.

It is a classic HDMI to USB converter. It converts the video to MJPEG format and is compatible with the UVC standard, working without drivers on both PC and Android mobile devices with the appropriate apps such as OBS for PC and USB Camera for mobile
