I bought this module and I consider it a waste of my money. No (zero!) documentation. Emailed support and received no response back. I had to pay a developer $300 to fix the problems for me. I would never buy any software from this company again!
Owner's replydear sir, we offer all our support, we try to solve all problems, although in some cases do not depend on our module(for free).
The module also is easy to configure.
