Compared to other toolboxes like this one from Revain, this is a very good deal. It's quite strong but tends to flex a bit when twisted from above. The boxes will stick but with a bit of WD40 it will surely go away. The only thing that bothers me is the lower sloping drawer, it had to be pulled straight out because everything that is at the level of the drawer hits the top when closing and does not allow it to close.
