Parts of the assembly were very awkward because there were no holes drilled for the screws to secure the brackets. The instructions were also not great as single steps combined multiple similar steps which made it more difficult to interpret the diagram (particularly as the angle at which the unit was drawn had to capture each component being added which obscured how some were attached), and finally the top piece was mis-drilled (holes for internal attachments drilled on the nicely finished exterior side). Have had to return as a replacement part will take too long to arrive.
