Its a great youtube downloader. It does what its made to do quickly and without problems. It does require a one-time donation to do MP3s but with most of the free ones these days being virus laden messes, I think its worth it.

Amazing!
It's good to be able to download audio only or video with the same addon.

Excellent downloader and super fast download. Its after one donates that the speed increases.

Does exactly as described. Well worth the cost of registration.

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

Ease of use.
The choice of quality of downloads.
Makes it meaningful to save selected videos.

good

Didnt dowland audio and video uper then 720p.

The download speed where I live is only 1.5 megabits a second. This makes watching videos at any decent resolution a problem when I'm the only one using the net, and impossible when other family members are using it.
Since I watch a lot of tutorial videos, being able to download them to watch offline means not having to pause, buffer, scrub back and forth, repeat.
After using the basic edition for a while, I've just picked up Pro and gave it a try with a 1080p Blender tutorial. The transcoding is excellent and it will be a great help in the future.
Highly recommended.

Update: March 10, 2019. Still loving this app. The registration is worth every penny, and the little elves that transcode the videos on the remote servers have to be fed somehow. I've introduced another family member to the app and they love it, so we'll be donating again today.

Fantastic add-on, for every high quality format in video or audio you desire!

Do not work.

works great, very happy with it

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.

This is the best and ONLY video downloader anyone should ever use for Youtube! I will continue to use this ALL the time and recommend it to anyone serious about downloading videos. If you are looking for a free downloader, just remember that you will get what you pay for. Don't expect developers to do all this hard work just so you can have a cushy life!

That's a good apps

GOOD

ZERO !!!!!
