Your review: Item description says "Assembled", which is not necessarily true. The casters need to be mounted. Two of the four casters were difficult to mount because one of the four screws to mount an individual caster was inaccessible with a wrench, making it essentially impossible to tighten down the (provided) lock nuts. The solution was to find our own (non-lockable) nuts to get the casters mounted securely. Initial impression is that these cabinets are rather flimsy for the cost, but will do the job.
