Good overall quality. Only real issue I had with it is that the borrow board was stapled together and that there was a split where it was stapled next to a small knot in the wood. When fully loaded down a hive weighs a lot and I don’t think staples will hold up, so I will be screwing it together to be sure. Other than that the quality is very good. We really needed a couple supers for other hives so we assembled these and the sizing was spot on. I would recommend upgrading to a wood bound metal queen excluder. I definitely recommend this as a purchase. I will be buying another one soon to keep up with our growing needs.
