Packaged well, easy assembly instructions, they give you at least one extra of every assembly part (screws, etc.), fairly sturdy, soft close on the drawers, pre-drilled install holes on most screws (though not on the glass doors themselves, but the wood doors had them).
Overall really good quality for an easy, modular unit. Just FYI, the doors are interchangeable on any of the 8 pieces on this unit. The 32" pieces (in the middle) come as one piece each (top and bottom each), and the four smaller pieces are all independent units. This means you can configure this unit in any way you choose.
Be aware when assembling these that you have to make sure everything is square before you screw them together. If not you can have very slightly uneven cabinets next to each other. It's barely noticeable on ours, and I'm not that bothered that I'd consider taking the whole thing back apart and re-squaring it (if it's even possible after the first holes have been made). I just rushed on that one, which is my oops.
