I would want to see how this does in the real world for a few years before pulling the trigger, and especially in the northern U.S.
As someone who has kept bees in New England for several years and who has a mentor who has been at it for 40 years, extruding honey is the least of my worries. Mites, winter, and dry summers are way, way bigger problems than extracting honey. I have to wonder if people with these hives will be leaving enough food for the bees to over winter.
