The ability to have an event that can be connected from any device! I love how easy it was for people who couldn't attend in person because they were out across town to still come through our virtual events without issue (and we had over 10 different attendees). There's nothing about this product with its functionality as far as what you'd like but there are so many other things - just make sure your business needs support all features before choosing which one best fits them. We use everything here at work including Slack/Skype meetings internally via Zoom & Google Meetings. Our internal team uses these tools daily along side each others' availability throughout time zones. This has been fantastic when meeting offsite since everyone could virtually participate regardless where their location may've changed during normal day hours working life.
