I bought meetn few months ago for teaching OSCE (clinical interviews). It is financially more cheap as compared to zoom. It has more capacity for attendees to join the webinar. The audio and video quality was alright in the beginning however, there were few issues. Issue 1 - video freezed at times. 2. In the chat, at times I had to paste a long question for clinical scenario but it used to cut the question after 2 paragraphs so had to ask my students to see the WhatsApp message to see the full question. Issue 2- No whiteboard to teach. Issue 3 - background images are gloomy. If you can fix these issues then you will be in the front line.
