I do not even remember when, but a few months ago I got six of these queens from dspdrew, and one of them actually turned out to be fertile. It took about two months, but one of her brood actually developed into a worker. 
Right away the worker is not doing too good, but there are a few more on the way now. The other five queens are likely infertile.
