I bought a complete Ross Rounds Super last year and placed it on one of my strongest hives, following directions that came with it. The bees never touched it, so I wound up taking it off. I added it to what is by far my strongest hive this year. To date, I have gotten 10 gallons of honey off this hive this year with plenty more coming. And alas, I still have an untouched Ross Rounds Super in the midst of all that madness!! (Actually, I removed it today, disgusted.) I have requests for honey with comb in it and was planning on using the Ross Rounds to put into jars with the honey. I guess my next venture will be to make one of the boards to hold inverted jars so the ladies build the comb in the jars. If anyone has had success with Ross Rounds, please tell me the secret.
