I like that it is easy for anyone who has never used video conferencing before (like myself) because of its simplicity! It's also very good at what you need out-of -the box so there isn't much setup required when using this software as opposed to other options which require more time/effort in order have everything set up correctly from scratch first off.
The only thing about GR we dislike are some issues regarding user interface design where sometimes things can be confusing if not done right or know how certain functions work but overall great product all around!! Definitely give them try they offer amazing customer service too :) We use their services during our office hours while working remotely via Zoom meetings etc..
