I was looking at one of these at Dadant. It is a very sturdy well built unit. It has re-enforced holes in the bottom so you can fasten it to the hive body. It is pricey at $22.80 but when I think of no more hive staples and no more damaged hive bodies it doesn't seem so bad. I have a couple of question for SBB users
1) Is the "hive trash" buildup on the bottom board going to mean I will have to remove and clean these yearly?
2) Are you folks wintering with these in the north successfully or are you using an insert to make them solid in winter.
3) Any other observations?
