Terrible.  By far the worst product I have purchased.  We put furniture together all the time.  The bolts broke.  The screws are too short so you can't actually put the unit together.  If you do manage to get a clip or 2 to turn all the way it fractures the hole.  This will make the unit very unstable.
It is a good solid unit and would be beautiful but the manufacturer probably sourced cheaper screws and bolts which makes the entire unit unstable.  I would give this no stars but that is not an option.
