I strongly recommend it.
I had some issue at the beginning with the self-refresh of the first comment without loading the entire page, but the support was very helpful.
After finding out the "Comments container selector" in my theme, I've just added the following lines shared by the developer :
Comments container selector: #commentsWrapper
Before select elements:
(jQuery('MYCOMMENTCONTAINERSELECTOR', dom).length > 0) ?
jQuery('MYCOMMENTCONTAINERSELECTOR', dom).wrapAll('<div id="commentsWrapper" />')
: jQuery('<div id="commentsWrapper" />').insertBefore(jQuery('#respond', dom));
Everything is working like a charm.
