I was immediately encouraged by a very helpful reply to a pre-sales question. It was extremely useful to be able to create a test site to fully test drive the plugins - which are very well documented.
The plugin and premium add-ons were easy to set up and configure. I have found them to work very well and provide the exact functionality I needed on my site.
Support has been the best I've experienced with a plugin. The company even went so far as to provide me with some code to meet a bespoke requirement I had.
I wouldn't hesitate to recommend.
