The shipment was received in battered condition.  It was covered in tape. All four corners were torn open.  Two shelves were slightly bent.  One we were able bend back a little.  The other worked in the bent condition.  One of the corner cylinders was bent and we used that shelf on top and rigged it.  We should have sent it back, but didnt notice some of the damage until we were assembling it.  Not happy.
