Since there is no thumbs up button, I just wanted to second what Mr.Dave stated.
I was on the fence about trying this but found their website off-putting. I am always leary of a company that has no information about themselves, e.g. location, contact info, etc., on their website. Add to that those three ambiguous reviews, with pictures, and I have opted to pass on trying this. Their website was only recently registered on Aug 31 2019 so I assume they are a new company and still sorting things out. That is apparently why, as you stated, “this seems like a beta test, not a v1”.
I currently use Soft Organizer with IOBit Uninstaller as a back-up which sometimes finds things S.O. leaves behind and will stick with those. Again, thank you for that informative post.
