I bought this in a rush following the Acyba name. It does what it says as a standalone extension just great. Unfortunately in my case i wanted integration with components and providers other that the ones listed by the developers. These guys now support! they offered and developed new integration for my needs.
Till now i have no problems whatsoever, all requests are developed or on development, so this is a 5 star. Great work guys!
this is great extension, actually it rocks! far better from what i have tried till now although the subscription extentsions market is quite small. worked with no problems from day one.
very "friendly" with other extensions as well and deeply customizable. a better graphic interface would be welcome.
