The only problem I had, most likely due to my lack of experience with Joomla, was that I was trying to upload and install the extension via the Joomla installer and getting error messages. I emailed the developer and received a quick response that I should install the extension via the JCE installer - not the Joomla installer.
There is a video tutorial on the developer's website that probably explains this, however, I could not get the video to play. I suggested to the developer that they include some documentation with the extension. Thus, a 4 star rating instead of 5.
Well worth the 2 buck price!
