No MP3 download possible, you would have to convert cumbersome.

It at least works, which is something that most other YouTube MP3 format downloaders don't do. But even when I requested an MP3 file, it downloaded the video in MP4 format, and it did so at a very low bitrate, making for a sub-par audio line. Would not recommend.

No thx!

nenabízí stažení kompletního videa (audio+video v jednom), takže si to strčte do prdele

It does not work.
It asks to install other software.

You should block installation on Android as it does not work on this platform.

Downloads are too slow.

Will not download most videos in 720

Does not work. On any YouTube video, clicking the download button just results in "Cannot detect url_encoded_fmt_stream_map or adaptive_fmts"
