Product review: It's hard to review the "offered" product, because they delivered something ELSE.

This AppSumo SELECT says this is for the "VideoKit", and all the screenshots show the "VideoKit", but when you redeem the code and download the DMG file and install it, all you get is the "Video Converter" app, not the "Video Kit".
And even after clicking the "Upgrade" button in-app and registering the license code, while it then says "*Pro", it is still just "Video Converter" (which includes only Video-Converter, Video-Compressor, Audio-Converter, Audio-Extractor, GIF-Maker .... and not all the rest of the VideoKit features advertised in this AppSumo deal).

Sorry AppSumo, your Quality Control failed here.

Now, with that serious negative factor out of the way, the converter/extractor features look good, run speedily, and the app is very easy to use.
