Дополнение не является полностью бесплатным. Бесплатный доступ фактически представляет собой пробную версию примерно на 51 скачивание, после чего для продолжения требуется PRO. При этом ограничение количества скачиваний заранее явно не указано в верхней части описания дополнения.

Fantastic

Wonderful Program! Works exactly as it should. Thank You for making it.

This is extremely great add-on, it helped me a lot to learn to edit by recreating the YouTube videos created by others. I would love to thank the creators, and I am also assuring you that, I will donate some of my earning, to help the creators and also keep the add-on free, once again thank you very much for this wonderful extension!

Oh boy, this is exactly what I needed to get my collection of Japanese pop women on my phone :-)
Have had no issue at all; every time I pressed the download and pick the MP3 256kb it went pretty fast: BAM ! Another one to my collection.

Very happy with this tool! fast and easy to use. Well done.
