Here's a question for you. Has anyone used or know of anyone that uses this piece of equipment? I have kept bees since 1997 and have never heard of such a thing until this year. I'm very curious to see if this actually has any value. There is nothing written that I can find other than what I read in a supply catalog. I can definately see both advantages as well as disadvantages in using it. Please let me know what you think and I will let you know what I find out, I'm goint to order ten of them this week and try them out in several different situations, in different yards.
