OneSpace Essentials 5-Tier Bookshelf, Black

I ordered 2 of this product on Aug. 18th. As a prime member, I was hoping for 2 day delivery. There was no tracking number so I couldn't tell when the items would be delivered. 2 weeks later, I received ONE of the bookcases and both sides were broken in half. Over 3 weeks later, still no ETA on the second bookcase. Can't refund/exchange till the second one arrives. When? Who knows, because there's no tracking number and no hint of how long it'll be. Ordered another one. Began to assemble. The instructions are lacking. You have to try to figure out where some of the parts go, and which way the pieces fit by looking in the pictures. The screws don't screw in tight. After you get it in about 2/3 of the way, the whole unit goes roundy round and won't tighten and secure. After assembling the whole thing (no easy feat to do), The front panel was backwards. So had to take the whole side apart to try to get that one piece turned around. The screws came right out! they didn't screw in tightly to begin with and now I had to deal with a loose screw while trying to maneuver turning one part around. The holes and screws didn't line up, so it made assembly that much harder. Since it's particle board, you can't use much force because you'll damage it. Frustrating assembly. Once assembled, it seems sturdy enough, though I'm not sure I'd buy it again... The dealer should be required to provide tracking for the order. More information should be provided for the assembly. Someone should check the line up of the holes. Someone should check why the screws don't screw in all the way.
