Shinjiru - Thoughts?

Question/Discussion: What do y’all think of Shinjiru?

Longer Description:
Shinjiru is the only domain registrar (that I am aware of) that allows users to purchase less-common domains like .io and .to. They also seem to be highly privacy-eccentric even stating:

“[their] mission is to protect privacy, a fundamental human right”.

However, they seem to be lacking any form of reviews online.
Therefore, I wanted to start a discussion to see if anybody here has used them or knows of anyone who has reviewed them.
