It's a robust tool that has is UI and can handle a lot of traffic efficiently. All basics are working very good (presentation mode, meeting, permanent room etc) but there are things I don't like.
Branding on the footer cannot been removed even at the 5 codes stack. Also we started with one room only, then deal changed to 2 rooms per code and then 2 rooms or 100 participants for EACH additional room.
Export frame rate of recordings was added to the info later and it's a huge deal breaker as 12 fps is pretty low to sell a webinar.
Thing is the attitude of being hard on those details that I don't like. It's like trying to push a sell on every corner.
Tool is good and versatile though.
If they make rules of the deal more flexible would be easily a 5 taco deal.
