The module is very well done, simple to configure and use.
I did have a problem which was not because of the module, the fault was in my own page.
I asked some help to the support team and they sent me a new php file to fix my problem in about one day!
Amazing team, reccomended!
If there is something that has nothing to do with being rude is the support of these developers.
The extension is very good and highly customizable. I had a problem with some features that was not exactly what I needed, I provided them an ftp account and they fixed everything in the kindest way anybody could do it.
Thanks a lot!
