I have only used the product a couple of times so far and it works great I am streaming simultaneously to Twitch and MixCloud and I did not have any issues. I like the fact that we have many options for destinations.
I specially like the possibility to have separate destination groups, in my case I produce two different shows and I can have 2 different groups setup for each of my shows, so in my streaming software I only have to select the one of the 2 switchboard destinations depending on the show I will be streaming.
I am giving 4 tacos only because a feature to consolidate comments from all the destinations in one place is not available. Hopefully it is in the roadmap.
