The box arrived undamaged & as I started unpacking it I was impressed at how well protected the pieces looked. Unfortunately that doesn't mean anything if items were already damaged before they packed them, which is obviously the case. Once I actually got things out of the box, I found that all of the shelves plus the top piece had bent edges. The bent places on the shelves were minor enough that it didn't wind up affecting anything, but the top piece holes couldn't be lined up to attach one of the corners. Fortunately, none of those damaged places showed after assembly.
Here's the main problem though. The screws used to put the whole thing together (marked as item "N") DO NOT FIT!!!!! Either they supplied the wrong screws or all the holes in the cabinet are too small. I've accumulated a decent amount of screws & bolts over the years, so I figured I could just use something I had on hand. Nope, not a single thing fit. I did find some that would at least hold things in place ("barely" not "securely") enough to get it assembled. Once all the parts are in position it holds itself together "fairly" well. Because of where & how I'm using this, in my case I was able to make it work well enough. But it is NOT properly assembled - for most people this would not work. This is a serious problem from the manufacturer.
To its credit, I do appreciate that the shelves are fully adjustable. Some cabinets like this only have limited places where the shelves can go.
