Been using it for a while and it works great.
Does take some small changes i believe to set up properly.
I haven't made much changes yet, but will have to examine how to get the most out of it.
Important thing I have noticed, is you HAVE to empty the page cache every time you update the website, post a blog, etc. Otherwise it will look like it changed to you as admin, but users who don't have admin access will still see the not updated version of the website.
