The table arrived broken at the slider for the extension.  The white glove delivery contractors didn't catch this.  When I called Wayfair, they were really helpful and put me in touch with the manufacturer who determined within 24 hours that they would replace the table.  The table won't be delivered for 3 weeks which is annoying as it's the day after Xmas and I'm expecting company.  Just thankful that it's being replaced at no charge to me and hopeful that the new table doesn't have any issues.
