Just what I needed!
I love it! The design is very pretty and well made. Easy to set up and hardware included but please do yourself a favor and build the sides and top first, then the front door and the back part last. I made the mistake of trying to put the top last and I had a hard almost impossible time taking it apart. Once the parts click in they stay! So that's not a bad thing! Definitely durable and thick material, waterproof because everything sealed perfectly. I love the size and how roomy it is. I installed a 4x4 wood piece and added cement to it, once it dried I put the post on top and it fit perfectly. I just made sure that was leveled. Installing the actual post and mailbox after the wood post dried only took a few seconds with the screws already included. I added the numbers easily (sold separately). I love the finished look!

PVC mailbox with post
These mailboxes were pretty easy to put together, and they were pretty easy to mount. The hardest part was taking the hole to put a 4 x 4 post into the ground and concrete that in to set the post on top. The only thing I would suggest is that if you’re going to use this mailboxthey don’t don’t provide enough support for the post itself. The plastic needs to have two or three more screws with washers going around up further on the post not just down at the bottom it’s a little wobbly otherwise otherwise it’s a really good. It’s adorable. It’s quality. It’s a large capacity and functions the way it’s supposed to a door opens very easy. They don’t don’t provide enough support for the post itself.

Beautiful replacement or new install
This is a perfect replacement for your tired old mailbox, or even a fresh install. This box is larger than a normal box and will allow for slightly larger packages to be delivered instead of taken to your door. Pay attention to the instructions and double check before clicking the parts together, because it can be a slight pain to get them apart, but that's a good thing. If you already have the post in the ground and it's in good shape, this mailbox and post simply slide over the top and is secured by screws. Don't deface your new box with cheap stickers or the like, as you can order beautiful number plates or plaques to attach by adhesive or screws (via Amazon or other). Can't say how long it'll last, but it feels very sturdy and made with thick plastic. Should hold up for many years and at this price, easily replaced when the eventual time comes.

Good mailbox
It’s just OK. Decent quality but an edge on my post wasn’t fully vacuum formed, I think it’s going to be OK so I didn’t raise an issue. It’s easy enough to figure out assembly, but the instructions are average. They don’t tell you specifically which screws go where and it was confusing for a moment when I saw sooo many screws/bolts/nuts that don’t get used. In the end, it’s just 4 bolts to hold the box to the post and 4 wood screws to hold the post to your 4x4. I show a picture of the leftovers - a pretty large and random collection of parts! The size is very nice. We will appreciate the extra width and depth of this box. It looks nice. I do wonder if it will hold up to the snow plows with its relatively skinny post compared to many other plastic mailboxes.

Durable. Large enough for magazines, newspapers.
Very sturdy. Believe it will hold up well. Made the mistake of trying to fit it over an existing 3x3 inch post. Will need to dig that up this Spring and replace with a 4x4 post. Who would have thought anyone would have previously used a 3x3?

This mailbox is just beautiful, and neighbours have complimented us on it. Since we installed it, a couple of other neighbours have followed suit and got the same mailbox. We live on a rural road and I feel like it makes the entire street look better. We look like a neighbourhood now, not just a road with houses on it.
