It was frustrating putting this shelving unit together. One person can assemble it but two people will make it a lot easier. The product was delivered rather quickly but as we started assembly... the holes dont align and the shelf wasnt sitting flush in its place. I called customer service and they quickly rectified the situation by sending us a couple new ones. It was a lot better this time but a hole didnt align when we got to the bottom. At this point, we had already taken out everything from the box and even if I thought of returning it, I felt it was more of an inconvenience so since its only a couple of jokes that needed aligning, my husband just bought a drill bit for 
metal and we tried to secure the shelves best we 
can. I just dont think it shouldve been that hard to put together. Its a clean looking pice for a minimalist modern style and that  part didnt disappoint.
