I have a number of websites in the accounting and business coaching industry, and using this extension has made it so easy to setup and manage my membership based websites.
In the early days there was the odd time were I noticed the odd bug here and there, but each and every time I reported the bugs they were fixed ASAP (sometimes in just a few hours)
These days it just works! I don't have to touch a thing or even think about the technical side of my site, and the money just keeps rolling in month after month from my membership sites.
I'm more than happy with the extension and the support received.
