Useful, but has bugs
I use Explain Everything for converting PowerPoint presentations to videos. It works fine for plain text, but not for graphics. During conversion it changes the font and size of characters, so any graphics that are related directly to text on a slide will be misplaced, since the relative positioning of the text changes. It also messes up the indentation for lists, and cannot convert special symbols correctly. This would be a great product if it could accurately convert PowerPoint slides. Until then, its OK until something better comes along.
