I bought an OH almost exactly like this two years ago off ebay. It was super sweet, and I used it for a year, but then the bees got super angry. Like totally unmanagable. An angry OH in your room doesn't add up to good news, so after several attempts to get them under control, I said screw the whole OH thing for a while, and put it in my back yard.
About a month ago I figured it would be fun to try it again. Went to the back yard to get the oh and it just fell apart. Termintes and rot, the whole thing just disolved in myhands. So angry.
So I spent my whole winter break rebuilding it. It was fun. If you want pictures, I'll post.
