With my many years as a website/Joomla developer I have used too many 3rd party add-ons to count.  I was pleasantly surprised by both the quality of the written software and their continuous support whenever I had a problem.  Upon purchasing the Advanced Membership Suite, it was evident that they seemed to have covered all the bases with regards to features.  When I did have an issue, they were prompt to respond and troubleshoot any problems that I had been having.

I would not hesitate to recommend their products to other developers.  Kudos to your team!
