I ordered the 3 piece nesting tables w/ slate tops.  They are well constructed, nicely finished and the slate has a great combination of colors.  One slate in middle table slate top was not level but at an unreasonable angle.  I call customer service and was promised a replacement at no charge.  I was told that they went through the middle tables in stock and they sent me the best one they found.  It arrived with a similar but somewhat worse uneven top problem.  No sense in asking for a third replacement.
