Its developers thought about all the needs that users might have, all what you need this extension has it, it does exaclty what it says.
Ease of use
You don´t need to be an expert to use it, I learned how to use it the same day I bought it without the need to read any tutorial.
Simply excellent! In a few hours, sometimes minutes, I´ve got the best support.
They have available all what you need to know, anyway I think it´s almost unnecesary.
Value for money
I would had paid more for this extension.
