Tabletop was defective, the paperwork inside instructed me to contact 3d concepts to report damage. They asked for pictures which I supplied and determined that it was a defect and they would send me a replacement topm after several. Weeks and not receiving the table top I played phone tag with 3D. After two weeks we connected and at that time was told it was not a part they could replace and that the whole table had to be replaced and they could not do that.  It was now over the 90 days.  We did work this out and they replaced the table, although I believe they blamed it on shipping damage.  My suggestion to you is to remove the paperwork from 3D so that your customers just deal with you. 

Pros: The table was replaced. 
Cons: It took from Feb till April to resolve
