Spun up the container about a week ago. Made it my default search in Firefox. So far I've been happy with the quality of the results although I will admit there is a perceptible lag when submitting searches, compared to google/bing/etc.... I imagine that's mostly to do with the fact that it's waiting on multiple search engines to fill my request.
I do like it so far. I figure with some tuning I could get the response time down.
