Review: Would recommend. Great quality. Wish it came with more than 2 keys. - Great quality heavy duty box. Would absolutely recommend this to someone else or a family member. I think the description says bronze, but ours was just actually gray and based on another review that was what we wanted. The finish looks and feels great and I believe will hold up. A few neighbors already gave compliments during installing. Would recommend a white mount found here on desertcart for it that’s a thicker plate. Just wish it came with more keys. It only comes with 2
Review: ⭐️📬Perfect! Recieve Your Mail Safely & Securely!📬⭐️ - I am so glad we invested in this mailbox! Not only does it give a better curb appeal to our property but also helps us to recieve all our mail safely and securely. (Please disregard the huge orange concrete pole that was placed on the neighboring property as that is their property line marker that they had painted with the bright orange) but as you can see the mailbox is very eye appealing to our property especially with the added custom decals we had bought separately! We live out in the county and have had issues in the past (which has been several years back) with our USPS mail, and packages not being recieved. Now that we have a secure delivery box up at our home, along with this locking mailbox we have had no issues since! I really like the pricing too, as it's very fair considering the features this mailbox has! Regardless of people knowing it is a federal crime to mess with people's mail and mailbox we all know things could potentially happen and to me it's worth every penny to be better safe than sorry! The mailbox is pretty universal when it comes to what type of poles you use to mount it too, and it's an extremely sturdy mailbox made out of very well built, and strong metal material it was made with! We also appreciate the capacity this one holds as far as mail and packages ad well. Our mail lady has had zero issues as far as it's performance and it's done very well for her! Great investment! ⭐️⭐️⭐️⭐️⭐️
