I tried it for two months and it was good, but not that much better that I'd spend $10/mo on it. The results were basically about the same as DDG. I can't really relate to all the praise I see about it.

However, I do have to say that, when I was looking for a very specific post, I spent around twenty minutes on Google and DDG and they came back with trash, whereas Kagi found it right away. In that one instance it was, indeed, fantastic.
