Only does video downloads and not MP3 conversions as it's "advertising", which is why even though it does do the video download (at least the one that it lists for the size on YouTube), I'm giving it a one star because it literally says "2) Single-click 256kbps HQ MP3 downloads" which is not true as you have to pay for the "pro" version or hope some other paid pro user has downloaded and only in the past 24 hours.

TLDR: Doesn't do a major feature of what it says it will do so 1-star.
