So... after using the tool (v1.9.2) for the last few weeks here are my conclusions:

1. Hulu: Working 100% as advertised. for me personally the tool was worth the price I paid for it for the Hulu feature alone. the downside is you can't easily queue up a lot of videos since you have to manually find and input the proper links for each video.

2. Amazon: It works but inconsistently:
 a.) as a direct downloader\decrypter (web-dl), it works when you have Amazon Video purchases that are not too popular or have been uploaded to the service in the year 2015 or earlier. Newer and popular releases can only be downloaded as .raw files.
You cannot know ahead of time if a purchased video can be directly downloaded or not. If not directly downloaded, you always have the .raw download option.

 b.) Amazon Prime Video can only be .raw downloaded. Not every single title can be downloaded. Some titles can only be raw downloaded in SD Quality-only.
This version of the tool is completely inconsistent and unreliable with the Prime Video subscription service.
If you want a Prime Video downloader, look for a better version.

3. Netflix: The most complicated feature of the tool. Finding and downloading the encrypted stream is done manually. No GUI for it.  Does not work with the latest version of Google Chrome (version 60 and up). You need to have specific older versions for the raw decoder to work. grabbing a 1080p link requires Windows 10 and Microsoft Edge browser.
Since it's too much of a manual work to try and download a netflix video, I have never had success with it. Only a handful of people who own this tool version (1.9.2) have successfully downloaded netflix.

If you're still interested in this tool, I'm selling it to anyone who wants it. I provide only very basic instructions for Amazon Video and I can not help you with Netflix. By buying this tool, you agree to and understand its limitations. More details in private.
