I'm a little sad about it. I've been using Cliqz from the browser search bar for a few months only because it's not Google. I'm probably switching to DDG now.
The search engine kind of works, but years behind Google. The most annoying missing feature is no "exact terms" search, which is a problem when googling error messages.
All considered I pressed the Google button at the bottom maybe half of the times, and I bet very few people would stick to such a search engine.

I don't know about Cliqz but this is generally true. We developers do a great job building (oh well) but if somebody doesn't do an even greater job at selling the outcome won't be good. The importance of selling vs building is 80-20 IMHO.
