unbubble a "European Search Engine"

[Brad]

It's a meta search engine and I don't normally get very excited about them.  But https://www.unbubble.eu/  is just odd enough that it caught my eye.  Odd because of the sources at least for the US version.  I have not tested it in depth but my first quick test indicates that it returns decent results for mainstream queries.

1. The selling point is no filter bubble and no bias.  No bias because they use many sources.
2. Privacy is another point.
3. In the US, I see 3 search engines as the heavy lifters: Exactseek, Mojeek, Yandex.  These three combined produce pretty good mainstream results.
4. I also see some results from: qwant, faroo, and some lesser Jayde Online directories, but not as often as the heavy lifters.

And therein are the reasons I'm mentioning this meta search at all: using Mojeek is a plus, but the addition of any of the Jayde Online properties are not something I would associate with privacy. 

Can somebody from UK, Continental Europe or anywhere outside the US try this engine and post what engines you see feeding the search I would appreciate it, plus your impressions.  Thanks.
