BEST APP EVER, when it's working. And that's the problem, as it seems to be down more times then it's up and working (on YouTube, using Firefox).

One of the problems (other than it being down - on YouTube, using Firefox) is that it's just not there, no, Sorry, We're Working To Fix This, or nothing.

It's back now, as of the time of my writing this review, but, due to YouTube's obsession with not allowing Ad Blockers, I can Download Videos, but can't actually watch them on the site (I REALLY wish this would work on the Brave Browser, as the browser itself blocks YouTube ads without having to install an Ad Blocker extension - which is odd, as it uses the Google Chrome engine, that they are able to circumvent YouTube ads, without getting the videos blocked).

When it's working, the videos are great, and it's worth the upgrade to the paid version (as long as you keep in mind, that if it's YouTube videos you're looking to download, that you may be frustrated with the intermittent service you get - would have given it 5 stars if it wasn't for that).
