Big and secure
Super happy with this mailbox. It’s nice and big. The color is nice and white and very durable. We had been having nail theft and now we have no issues because it’s nice and secure.

Solid, Secure, Built to Last!
I’m extremely pleased with the Architectural Mailboxes Oasis 360. The build quality is outstanding — heavy-duty metal construction that feels solid the moment you unbox it. It has a nice weight to it, which adds to the sense of durability and stability once installed. The security is top-notch. The lockability feature works smoothly, and the locking mechanism feels sturdy, not flimsy like cheaper models. I can finally say this mailbox really keeps thieves away — I’ve had no issues with mail tampering since upgrading to this model. It’s also USPS approved, which gave me peace of mind that it meets postal standards. After several months outside, I’ve noticed no signs of rust, even through rain and humidity. The finish still looks brand new. Overall, it’s a well-engineered, rust-resistant, and highly secure mailbox that’s worth every penny. Perfect if you want both protection and style in one package.

Fantastic product! My mail is safe!!
Exactly what I wanted! Extra large size because I get my meds by mail. Locking because I get my meds in the mail! Haha! I am really anal about anybody touching my mail. It could end up on the kitchen table or in the floorboard of the car! Don't touch my mail! I love having total control. I also told my mail carrier, do not give my mail to anyone that happens to be at the mailbox when you deliver. Put it in the box please. I own a Group home and any of my tenants could get the mail and who knows where it would end up! Hell, my first husband hid the water bill under the couch so I wouldn't find it? WTH? I have flashbacks!

Very good item, installation difficulty can vary
As far the the product, it looks very good, very large, and seems sturdy. Since the mail can only be retrieved through a key, it gives you a piece of mind from mail theft. The lock mechanism, however, is not very smooth. Key requires a bit of force to push in. And the price of the item seems very excessive. I'd think a fair price for this would be $50, but it's being sold for $100. Anyways, that's that about the mail box. About the installation. I'm reading the reviews, and most seem to have had an easy time installing it. I guess this depends on whether your mail post is adaptable for this mail box. My mail post wasn't. It was built by my previous home owner, and he custom made it. I had to get a 1/10 lumber, and cut it to length, drill holes, get myself mounting hardware which does not come with the mail box. To cut the lumber I had to use a circular saw. All those additional materials and supplies cost me another $25 on top. And that's assuming you already have yourself a circular saw, and know how to use it safely. Installation, not counting the drives to HomeDepot, took just shy of an hour. So I wouldn't say my installation process was "easy". It wasn't hard, but it took effort, and existing power tools. All in all, I really like the final result, and the mail box itself. Except it's just a bit expensive.

Great security mailbox
It’s so sad that I had to buy one of these, but when thieves try to ruin your day by stealing your mail, you gotta do what you gotta do. Anyways, it’s a large box, but not overly so. Installation was a breeze. I kind of wish the key was a 5 pin versus 4, just to deter some of the more sophisticated thieves, but it’ll do. Feels solid, like my post will go before the steel will.
