This is a great Video-Download-App. It has many useful features like being able to download from wistia, youtube, and countless other sites and choosing the size of the video.
Still the app is very easy to use, I never needed to check any tutorials or manual.
The support is very friendly, answers fast and helps you, till your issue is solved (after downloading 100 videos in 1 day, YouTube thought I was a bot :-) ...)
If this review sounds like I know the developers: No, I don't, I am just a very happy customer.
Bought the lifetime license and probably won't need other downloaders for a long time.
(I used several others until now, but never was really happy with any one of them, just with a combination of at least 3 downloaders.)
