Granted you can set up numerous plans at various prices etc etc, but should you wish to have a full integration with Community Builder, it simply isn't up to the job!
I wasn't looking for massive integration, just the ability to have 3 plans, one free and 2 paid, but I wanted the free plan to require admin approval, this side can be managed, but will the component send an email to a user once admin has approved, not a hope!
I spent days trying to get this to do some very simple things, checking the valanx forum for any hints and tips (not much use due to the refusal of the developer to even look at it) and searching the net for any clue as to how to sort this out, all to no avail.
Not a component I'd recommend for a stress free existence.
For a stress free existence, I would encourage people to get professional support if they cannot work out how to make software fit their application.
As for your case: We do not do support on our forums, but if AEC does 90% of what your use case and the last 10% is sending out a simple email, I wonder why you decided to jump ship and give us a 1 star review. What you want to do could probably achieved with a small workaround and the email MI.
I have reported this review for removal as it says very little about the software and a lot more about your use case.
