We use it across the organization -- we have about 700 remote employees and we use it to host meetings all the time. It's fast, reliable, easy to use on desktop or mobile, and it's incredibly simple to set up. Most of our remote employees are between 22-26 so it's great that they can use it on their phones.
If you have a lot of people who need to call into a meeting and you want to also video chat with them, it's a super useful tool. The gallery view makes it feel like everyone's in the room, and it's nice to be able to selectively share your screen.
