I was able to assemble the boxes and the deep box frames, but not the medium box frames. The grooves on all the side bars were too big to fit into the top and bottom bars. The company sent new bars, but I had the same issue. Then they sent an entirely new set, boxes and all. I haven't assembled them yet, but I'm impressed that they did that. I'll update once I put everything together. Other than the medium box frame issue, I like this hive.
