Very sturdy unit. The only thing is that i wish it didn’t have any plastic pieces (it has
these plastic cuffs that hold the shelves in place, so I wonder how long they will last. It should be fine as long as I don’t have to disassemble it and reassemble again). I also had trouble putting it together at first. The instructions say to make sure that the narrow ends of the cuffs are at the top however it is hard to tell which is the narrow end. There are some nifty arrows to help you, but the instructions don’t say that these should be pointed UP. Hopped on YouTube and watched a video... then it was super easy to assemble.
