It is very easy to use and they are very transparent with how to use it and how things are on their end. The free version feels very restrained, but understandably so. It's fine though as it is, and if you have spare cash, it's VERY worth it to upgrade.

I think it works great !!! yes, sometimes it stops it´s functionality because google changes it´s code to prevent downloads, but after some days the add on works again perfectly.

very good considering that it is a one person project

This is just the best Download to use for YouTube, you will love it also so give it a go you won't be disappointed...

This is the best extension for YouTube!!

I thought this would be a so-so addon, but it was great. Every time YouTube makes a change the problems are fixed. Fine customer service.

This is a wonderful add-on, particularly for instructional videos where I may need to stop and immediately review a small part that is more difficult to follow. I support the development whenever I am able so to do.

Great

Simply amazing add on which easily, and quickly (with the press of a button) downloads any video you need to keep from YouTube.
Had zero issues, this is the add on that just keeps on giving.
Huge thank you to the deveoper!

Brilliantly useful bit of kit - and great for saving videos that may only be daily / weekly /temporary.

It's a great tool, just the one I need, and works as expected.

Have been using this plug-in for a few years. Every time I have had a problem grabbing a video a patch has appeared soon after. When downloads are really slow being able to download and watch later is great!
Would definitely recommend.

Very easy, very good!

I've been very happy with this add-on (not used lately so I don't know about this very recent problem). For me it's fast and easy, no negative. I'd be happy to chip in if there was a free amount, US $10 is a lot for some foreign countries.
