I bought tier 3 and am very satisfied with this product.
Simple, easy to use, intuitive: I don't need to read any manual to use it.
Modern, professional interface.
Meeting video is smooth, beautiful, clear, and high-speed.
The feature can completely replace the Zoom software. Some features aren't there yet, but there are some that Zoom doesn't.

Currently the Vietnamese language is not supported, so I cannot attract many people to register for the webinar. We hope GoBrunch will quickly develop Vietnamese language support in the near future.

I bought a lot of meeting software, webinar at AppSummo and GoBrunch really worth it. Don't miss this deal, or you will regret it.
