i had to replace my old rotted wood post and dented  metal mailbox and decided to try this one.  All I had to purchase was a new wood post  - I just got an enexpensive 4 x 8 and cut it down to the correct height and small bag of concrete to set it in the hole.  My mailbox is sturdy and keeps my mail dry. I like the back door to retrieve the mail so I don't have to step out in the street. Very happy with Wayfair and their products!!!
