My only complaint was some manual tweaking needs to be done for certain lines of displayed text. But, that is tedious, not difficult.
What impressed me the most was how well as a component it worked, and its interfacing with PayPal. Those are, of course, crucial to any subscription-based website.
What was stellar, though, was the support. I had some conflicts with other plugins, but after submitting a ticket their tech support responded very promptly and figured out a solution. They were very accommodating and went above and beyond in their trouble-shooting.
It does take some set-up, but it is intuitive to the intermediate mind-set and the website's documentation and guides can help you from there.
They also have great tech support, working on an individual basis to help you with your problem. The same person works with you until your issues are fixed.
-Works as advertised
-Tech support is helpful and gets back to you
-Fairly straightforward to use
-Tech Support may take up to a day to get back to you, depending on your time-zone.
-Images must be uploaded directly to the image folder within the module; can't do it from Joomla's back-end
-There may be potential jQuery conflicts. Mine conflicted with JoomlArt's mega menu and RSComments. Contact tech support and they'll fix this right up.
-This is the MODULE, however there is a MODULE+COMPONENT available on their site. The bundle obviously costs more.
