I love the look of these, but it was next to impossible to install the casters.  The screws and nuts are tiny and somewhat difficult to work with since the spacing for the casters are larger than the holes so the screws go through.  It took far longer than necessary to assemble.  They are really cute and hold a lot of items, just wish the assembly was easier.   If they made the caster piece holes smaller so the screws don't fall through, it would be an ideal piece!
