The parts that the casters screwed into were not the same from the instructions and actually two different types. They also prevented me from using the bottom slot. Which the instructions show you should do. Very awkward to put together. Had to force a lot of things because it was flimsy and the metal not the greatest quality. Protip, instructions are bad and wrong. Put the caster screw-in things (not the actual casters) on first. They may cover up that first slot. Do not put the fences up on one of the sides until after you've placed the shelves. You'll have to take them out to get the shelves down otherwise. You get a hammer, it has a padded end, use it with vigor. Possibly get a second person to help because it gets awkward when you get to the top half. Despite how much of a pain in the ass it was to put together, it's honestly very sturdy. Like surprisingly so. Hence I'm rating it well.

Instructions not really clear about a few things. A couple steps would be easier with 2 people. It's fairly solid once you get it done.
