Query: Some poor welding and design flaws

Got this mailbox quickly, and was expecting to have the same quality as in the Architectural Mailbox I had just ordered for my home. This was to be a PTA mailbox to be installed in a school corridor.When we mounted it to the wall, the lid would not open! Should have had a different style hinge, as clearly this box is designed to be mounted on a wall. Had to place some washers behind the top screws to allow clearance to open the lid. Then, noticed that the weld on the back panel of the mailbox is bad and the back is separating from the side. Would probably return, but it is already up, and extra keys were made.
