If you teach at a university, or you are considering using this for classroom instruction, you may want to stop right here. These are the deal-killers:

1) Super expensive if you want to use it for classroom instruction. I teach 180 students a semester twice a week. By my calculations (found out after the purchase), I would be spending *minimum* over $400 a month just to teach classes on this platform.
2) No mobile platform support. If your students want to join from an iPhone, they cannot do it.
3) Lack of support/communication from the vendor. They will not respond to questions.

I bought this thinking it would be a cool, more-socially-centric app to have around than Zoom with breakout rooms. I found out, after the purchase, it had the (above) deal-killing drawbacks. The team will not respond to questions about the pricing.

The deal might be good if you were going to, say, teach a handful of seminars a month with a relatively few number of attendees. It also might be good if you were going to teach paid classes where you could make up the $1 per attendee overage fee from signup fees.

But be warned: in my experience, a company that does not reply to its customers, generally has a reason for not replying to customers! At least it was a less-than-$300 lesson hard-learned!
