That I could interact with students on live sessions at anytime without having to rely on the instructor to be online via other means (e.g. text chat etc.). The only downside is that the UI / interface can get complicated if things like multiple users are involved but I would imagine this gets better with future updates. It saved so much time in my courses where students complained about missing their course materials when they were on holiday or travelling away from campus. The ability to create a video and add interactive features is great. It's easy to use and to create. The editing can be improved, but it's a great tool. I haven't found anything I dislike. I would recommend this product to other teachers. I'm using this to create a video to show my students how to use a website. I'm able to add interactive features to the video. I'm also able to add a quiz to the video.
