TL;DR 0/5 star. They make you pay for mp3s conversion. Website says FREE.
Website tells you "
Quickly download and also covert videos, audios from YouTube to mp3 with our free YouTube video downloader plus converter add-on tool", "This software is free of cost with no download and conversion limit.", "Take advantage of this FREE online YouTube to MP3 converter for easier and quicker downloads". So it's free to download and free to convert.... but I have to pay pro? Scammers
