I've been using it on one of my personal servers and it's been a great experience so far. Especially paired with sshcode, which syncs your local vscode configuration with the remote server and runs it inside a borderless chrome window: https://github.com/cdr/sshcode
I use it in our lab, and it works very well. However, there's no multi-user support. So anyone who connects to the server gets served the editor with the same workspace.
That being said, I think they have the multi-user support in the roadmap.
