Before it was great now it just make you to download additional file just for medium res or high res and it doesn't even work.

DownloadHelper prompts to download additional pkg file (for certain video types) on a Mac which tries to install OSX.Bella trojan :(

Did not work for other websites. It could not find content.

Failed aggregating files...

Was good, but now they are only after the money! Now you need a shitty 3th party app for youtube or they put QR watermark on top of the video. Thanks for ruining a good app!

Программа полное гавно - ничего толком скачать не может. При закачке теряет источник каждые 30 секунд. Вы больше нервов положите, чем что-нибудь скачаете этой программой. Не пользуйтесь ни в коем случае этим ГАВНОМ!

I don't like your license. no! I totally hate it...

it requires a companion app

下载视频要合作软件，下载一个几分钟的视频下载完毕要合成一个多小时。

What is this 30 dollar charge for watermark shiz? Why be free then suddenly decide to charge money?

fcking sh!t

Can't download without companion app, external site, executable file. Get fucked.

Used to be the best. Now it downloads in a fair amount of time, then says it is going to take an hour+ to aggregate a 9.5 minute youtube video which is a still screen and music. If you cancel the aggregating, you lose it all, and I can find no way to stop it. All this since the companion app requirement although you can go without but the downloading seems to have been capped further then.
I'll find something else now.

Came back a year later and it has improved in time it takes and still tells me it requires a companion app, however, now there is a huge QR code all through the video. Is there a point?

Installs a big QR code on screen of all downloads. Spoils functionality.

Tried it out, but unfortunately it takes forever to download small files and uses a huge QR code in the corner of the screen to extort you to buy a license. I found and donated to an alternative software that doesn't do this. Thanks anyways.

Adding crappy QR codes to a video is a real no-go!

Just leave the video alone, no converting, no editing, no QR crap addition!

This add-on used to be great years ago but has become a complicated mess that fails to work reliably.

It lure you in and you need to pay for it, or it will add a awful QR code in the corner of your video.
