I had some problem firstly to make the correct template to import my products so I sent an email. Very soon Mr Giang contacted me and we discussed over Skype, a few moments later ha solved my template and we upload it! Working perfect and I was very satisfied with the support and help I got!
I will recommend this extension to all I know! Very good extension!!! I have maybe 30 000 + articles and this will help me a lot! Thank you! Keep up the good work!
