                I've had mine for about 5 years, and love it. I have had no issues with it.

                I totally agree this is the most cheaply made mailbox! Unfortunately mine is cemented into a beautiful stone column. The door fell off within six months and the flag will not stay up. This mailbox is very very cheap. I do NOT recommend buying it!

                    You bought one of the least expensive mailbox models offered by Home Depot. I bought the exact same one. It's been in service for over two years with no problems. That time included one hurricane and several tropical storms passing through here. The box and the door are steel, with ornamental plastic trim around the door, and an aluminum handle. I can't imagine what you are doing to yours to cause the door to get broken off, but I suppose some environments are more difficult. You can always buy a sturdier box at Home Depot. You might have to spend a little more. And hopefully complain a little less.

                      This is not a question, but I feel your frustration. I experienced the same thing after 11 months of normal use. I could not believe they used plastic hinge pins for such a critical part that sees the most stress. I contacted the manufacturer (Architectural Mailboxes) and they did not hesitate in offering to send me replacement METAL pins, which should solve the problem. And hopefully they are stainless steel or another rust-proof metal. Other than this issue, I think it's a very nice mailbox and the company stands behind their product. I just hope they rectify the situation for future customers by replacing the plastic pins with metal in the mailbox as-sold.

                            This was the mailbox only. There were predrilled holes in the base of the box to help mount to a surface.

                              Roxbury Mailbox is very nice looking large size
                              [This review was collected as part of a promotion.] Roxbury Mailbox is very nice looking large size mailbox. It is exactly what we were looking for, we haven't been able to put it up yet as it's still winter here. I just wanted to say how impressed I am with the size. Our mailman will love it as much as we do. And make his job easier by not having to come up to our house with what doesn't fit in the mailbox anymore. Although I do think I will miss seeing the mailman as often as I have.

                                I cut a custom piece of wood to mount the mailbox to, and attached it to the post and screwed the mailbox to that. Came out great.

                                The mailbox is beautiful, however not made well. The hinge piece that connects the flap/door to the mailbox broke off after 6 months.

                                  Lid broke off
                                  I’ve had this mailbox installed for two weeks before the lid broke off. The lid attached to the box by fully plastic bushings and plastic fasteners. Easy to see why two weeks of opening and closing would wear on these parts so easily. Very poor quality for the price. I’m already in repair mode for this new mailbox.

                                    These mailboxes are very modern looking. I love the baked enamel bronze color. This type of process should keep the mailboxes looking new for a long time. They are large enough to receive my prescriptions. My mail no longer gets crammed into the mailbox.

                                    ROXBURY POST MOUNT MAILBOX
                                    Installed mine yesterday, Installation was fairly easy. This does not come included with a mounting base so one will need to be purchased. Other than that I feel like it was a fair deal. I purchased a plastic base and it had pre-drilled holes that fit the mailbox perfectly. The mailbox has a lot of room and the finished paint looked really great. Hope to use it maintenance free for many years to come.

                                    Very attractive and plenty of room.
                                    We have always had standard size mailboxes and a lot of times the mail was too much or too large to fit in box without them cramming it all in and damaging magazines and or boxes, so we decided to get a larger one and I wish we would have got one a long time ago. The box is very attractive and has plenty of room for larger items and is well made for many years of use.
