+1 over here as well. I've been using it for years and I love it! Only good things to say about it, and it's infinitely more configurable than any of the other options out there. They're also constantly adding new features, I think they even have an Alexa skill for netplay now.

Anybody that's remotely interested should pick up one of the VRX's to play with as a virtual matrix manager and feed it your own test sources that you probably already have access to, (ie: IP cams, HDHomerun, files on a nas, or any rtsp stream really...) and see what it's all about.
