Excelente!! Super recomendo.

Top Funktion

super easy, 80% success rate

非常好用的軟件，可以輕鬆下載各種影片。

Very good, I needed to play with the settings, name domains etc so it even keeps the video title. I strongly recommend giving it a go and play about, its I think a lot easier than it appears. No recent manual so don't spend to long looking for bits that are no longer there. Play video, right click, download. It can sometimes be slow so check its all downloaded before closing your browser

确实很好用，今天刚发现了右键功能，结合按键及脚本功能，更方便了。

Excelente para descargar, un gran auxiliar en el navegador
