I've been lucky to have received one of the production version of these razors on a pass around and have it for the next week.
Colibri translates in English as ‘hummingbird' and I shaved with the 1.5mm gap baseplate for the first time on Thursday evening. I found that, as expected, it definitely felt like a large gap razor with a blade forward feel. It did give a pretty smooth shave, though. I never usually do three passes, but I was able to easily do that with this razor without any nicks, cuts, weepers or irritation.
I'm not a fan of super efficient and aggressive razors, but must say that I did enjoy this shave. I also reckon that it could, potentially, make for a very good head shaver.
