It has yielded fantastic results for me - 3-4 mated Queen per cycle in spring. But last several years I’ve been using it as a split hive (4 frame nucs) to make my Queens. Currently it is being used as a 10 frame beehive. With recent talks about Queens and mating Queens, just thought it would make a better usage for someone actually looking to mate Queens.
