Excellent piece of gear to give the older ATEM line of switchers the streaming capability of the ATEM Minis.
I bought this mainly with the idea of doing the same as the LiveUSolo on a budget and allowing a camera operator to stream back to studio to a ATEM Streaming Bridge with minimal training required. But it surpassed this and I've used it to stream beside by ATEM Mini simultaneously to other platforms, often with better results.
The one advantage over the ATEM Mini is you can scale and change your streaming setting without pausing the stream. Plus its Monitor Output has excellent streaming information.
One niggle I have found is that it occasionally refuses to stream despite pressing the On Air button or in software and requires a quick reboot whereupon it works flawlessly.
