Mini V2 : Works really well. Some counterintuitive things. Can't complain for the price.

Solidly built. Fan is slightly noisy (high pitched at lower speeds) but not unexpected. Autoresolution and frequency detection works well. A few quirks re PiP functionality... It's not very intuitive in terms of resizing the PiP, or choosing the right input for this. Also a few quirks when resizing/rescaling on the fly. Easier to restart the unit. Instructions are very basic and won't help you if you're not familiar with video stuff. If you've used other switchers and you are comfortable with general video weirdness then you should be fine. USB 3 output is straightforward. Presents as a webcam to OBS. Easy. Software control... Hmmm. Still haven't got this to work. Heavily OS and driver dependent can't have everything for the price, I suppose.
