We ordered two of these bookshelves. The first one we assembled no problem. When we went to assemble the second shelf we discovered that we were missing all the hardware - the connectors, bolts, key and screws. So we had to halt our project. We called the manufacturer to let them know we’re missing the required hardware and they will send a replacement but said it may take 2-3 weeks. Inconvenient to say the least. We just moved and have 10 boxes of books we’re planning to unpack but looks like we’ll be in boxland for even longer.
