Includes advanced Image/Media, File and Link handling, plugin support, and an Administration interface for editor configuration.
The only downside is that without paying you cannot even _report_ bugs (e.g. I've found a bug which blocks "paste as plain text" with Chrome browsers)...
Upon installation on most sites developed by big name professionals I cannot upload an image or simple things as text center, align left/right rendering it useless for my customers. If it doesn't work with the free version then why bother paying for it? I have moved on, unfortunately...
It replaced at least 5 extensions you would otherwise need to install.
The interface is clean. It is stable, every thing is optional.
Now you might wounder why the rating "FAIR" ** (2 starts)
Because the JCE system plugin (if ON) ads 1 to 2 seconds o any page load time. Nowadays everything that relates to website optimization and SEO should be a must, rated more than design. No use have a great looking website if no one visits it because of low google page rank... or if a user drops out because it takes more than 3 seconds to load.
Keep up the good work. And hope you fix this issue.
The "JCE system plugin" you refer to is I assume JCE MediaBox, which is an optional, separate extension for creating "Lightbox" style popups - http://extensions.joomla.org/extensions/extension-specific/jce-extensions/11357 - which in my tests on the JCE site at most takes only around 330ms to load.
