Review: Quality item for a budget price tag. - Very happy with my purchase! I priced and shopped mailboxes for several weeks before settling on this item. I looked at the pricey/ fancy brands, and all the trendy colors. Ultimately, I realized this was just a mailbox! It also occurred to me that I had never heard anyone, say: “Wow! Look at the pretty color and architectural details of that mailbox!” So, being the practical person I am, I purchased the black, metal, rust-proof, locking mailbox for 10x less than some of those other brands that people buy just so they can tell you how much their mailbox cost. Be smart - buy this one! You’ll be pleased as well!
Review: Sturdy built, easy to hang - Nice mailbox, was easy to hang. No problems setting code and my mail fits nicely. Not sure of waterproof/resistance as it hasn't been raining or snowing since I hung it, but it seems like it will keep my mail dry. Maybe need to Silicone around the screws just in case. I like that it opens from the front to collect mail and not the top as im short and couldn't retrieve everything from my old top grab box.

### ⭐⭐⭐⭐⭐ Value
*by T***N on January 10, 2026*

I use this to leave things outside for people to pickup (i.e. keys, payments, etc) and for people to leave things for me when I’m not home. I didn’t want to install a mail slot in my door for obvious reasons. Though this box was one of the less expensive options it’s surprisingly sturdy, the codes are easy to change. The only negative is the transparent plastic “window” at the bottom…..it allows people to potentially see what is in the box. I like it and for the price I think you get a good value, I wouldn’t use to store anything expensive; but as a secure dropbox it works great!
