We received the order in a timely manner, and all parts were provided , but there were a number of design flaws in the cabinet:
1)  two of the corner lock hub ports were too large for the metal lock discs that are supposed to secure a tight fit; so there was a visible gap and a compromised join at the left corner of the unit.
2)  the base shelf has a u joint bracket that secures the shelf to the back of the unit; this is supposed  to be fastened by screws , but the screws were too short to secure a proper fit, rendering the bracket useless.
3)  not a design flaw, but one of the shelves arrived with a large white streak on the front..
