I've used several video download tools over the years, but I took a chance on SurFast Video Downloader and I'm glad I did. The UI of a lot of these tools is very developer/hacker-y looking, but this one is a lot more refined, and it does a great job of grabbing videos, with several options for how to do that:
- Using a Chrome extension to do it right in the browser (I don't feel this listing makes enough of a big deal about how time-saving and helpful this is! Lots of downloaders don't have this)
- Monitoring the clipboard for video URLs, so copied addresses automatically start a download when switching to Video Downloader
- Manually pasting URLs into the program

It doesn't grab every video from everywhere, but the list of sites it does work with is pretty vast. Plus, unlike a lot of Chrome extension downloaders, this isn't full of gotchas and upsells. This is not a capability I want to pay a monthly subscription for -- although that said, I use this program several times a day to time-shift my viewing to my offline hours, and it works so well that the one-time $19 fee feels too low!

This one's a keeper!
