I haven't used them yet, but I like the way they look and I like the distance between the slide-in bottom board and the screened bottom. Also feels very solid.
The cedar bottom boards are well-built and handle the elements, especially when treated with tung oil. We were especially impressed with the slots in which to slide in verroa mite boards.
I am currently waiting for delivery of the nuc of bees, then spring will be close at hand...I hope! I am new to bee keeping. Last winter I made the error of insufficient air circulation...among other errors. This bottom board assembly will be better than the solid bottom.
The item arrived on time in good condition, nice well done.:))))
It takes a while to get their bee hives and frames but they are high quality. The tolerances mean a long use life. Clean and tight.
