The best thing about restream is that it's easy to use and has all the features you need for any business or organization.
It can be used by anyone with little experience in video production. I have no complaints at this time but if there are improvements I would like to see they should focus on making it easier to understand what each button does so less experienced users will not get confused when using the software. We stream several events per year through restream and we've been very happy with how simple it makes things compared to other services out there.
