I needed to display videos in a responsive manner (so that their sizes get adjusted depending on the screen size) and this plugin does that in a very simple way. We only need to put a video URL (e.g. Youtube URL) in the editor field.
Furthermore, the plugin also supports displaying a video from a custom field (as opposed to from the editor field). I got to know this functionality thanks to a very quick reply from the plugin developer.
Five stars for good plugin with good developer support!
