Don't waste your time, it works for a few days then stops. I even paid for the better downloading and still same issues. RIP OFF if you pay

Didnt dowland audio and video uper then 720p.

Do not work.

Works for what it is but sucks ram and internet bandwidth. Very suspicious... perhaps they're mining bitcoins behind our backs but don't trust this anymore.

ZERO !!!!!

Wants money for the mp3 download. Don't bother installing.

最基本128K都要付費後才可以使用，我覺得不行

Requires paying for and installing adware to use.

I didnt get any downloader all I got was a site with russian youtube videos and channels and ads.

pay 2 win

Just doesn't seem to work with FireFox 58.0.2 64 bit under Linux Mint 18 w/ Cinnamon desktop. Scanned for support but found no immediately useful help - only submit a form and wait for a reply. I am out.

The upgraded version works but the licensing process is garbage. You get a PayPal receipt that does not include any licensing info and that's followed by a sketchy one that will likely go to your spam folder. If you use outlook.com it will refuse to stay in your Inbox and eventually you'll empty your spam folder, forgetting about the email. You're going to need the email because the extension will downgrade itself to the free version and the only support the developer will offer is to give him another donation and try to save the email this time. Shame on me for trying to circumvent YouTube's usage restrictions, shame on the developer for a poor licensing process (I'll assume that the downgrade is accidental and not an attempt to milk donations).

Simply doesn't work! I have installed it on Firefox for macOS, restarted my browser and there is no sign of this download button.

I donated last week thinking that I now had the pro permanently. Come today to download they want another 'donation'.

It appears that you only get to download as a pro (1080p), if you keep your browser open. Once you shut it down and go back guess what, another donation required for HQ.

What a rip off.

Requires paid "pro" to download 1080p.

Video-Download ist nur in tiefer Qualität möglich.

CAnt download mp3s with this, It asks to go for pro version. #SAD

Does nothing
