Other than a period where Google/Youtube were shutting free download extensions and programs down left and right this one has always been trustworthy and worth the pro price if you're downloading more.

Besides some UI issues, would recommend

I've been using it for years. Every now and then when YouTube changes it's download infrastructure, it takes a few days to a couple of months before it works again. But in general it is very recommendable, does perfectly and easily what it should.

New version is pretty nice. Just wish you could disable the popup window that notifies the download is complete, there's already the built in status widget on the page and Firefox's own download manager popping up at the top. And if we could edit the download options to e.g. remove all the MP4 options so the drop down is shorter would be nice too.

Seems to be working great. Good app. Good job. Great.

Works

Easy to use but has a limit of 10 downloads and then you need to buy it.

Great App - Lousy Marketing, Nag Screen is Anoying

very useful, Thank you!

It works just fine. Not the best UI. But it works.

Easy to use. But will slow down a bit the computer while downloading video. Also, sometimes, it will convert the video to MP4 but sometimes not. However, still, it is a good free software.
