Package was delivered with a missing screen #8, and 2 #7's instead, which took forever to figure out during assembly given all of the other parts to sort through. Waiting 2 weeks now for a replacement part to ship, after having to make two requests because the first request was never confirmed?? I only have 1/4 of it built so far but the product itself seems decent, and the cats and I are very anxious to get it completed. But the experience so far has not been fun.
