Great Mailbox
Exactly what we needed. Great price. Very basic assembly. Good size mailbox. Edit… The front door of the mailbox broke off within one month of having it. I contacted customer support & they are sending me a new front door for the mailbox. I was disappointed it didn’t last longer, but happy they are willing to take care of my issue.

Great product!
Installation was a breeze! I purchased a 6 ft 4x4 for mailboxes and buried it 3 ft in the ground. It is solid and looks great!

Great mailbox.
Simple to install. Even though my original post was only 12", and this one requires 36", so I had to add 24" and connect it with rebar. Ok, not a huge deal. But it's nicely constructed, looks great and so simple to assemble and install. I would recommend it to anyone.

More Heavy Duty
Strange thing, this mailbox. A few years ago I bought a similar item made by the same company, which a delivery man promptly trashed. I finally got around to replacing it and to my pleasant surprise this new box was not only cheaper, it's of better quality. The mailbox and hardware are more heavy duty than the old one and the doors are held in place with a magnet, rather than with an annoying "snap."

So far its a good quality unit.
Came with all the parts, clear instructions. easy install. just need a post hole digger. screw gun and ratchet and 1/2 socket. plus the 4x4 cut to correct length and either the expanda foam or cement for the post.

Good Mailbox MADE IN THE USA
This mailbox seems to be made of good quality plastic. It has 3 main parts, a bottom post support, an upper post part that has the mailbox bottom incorporated into it, and the U shaped mailbox that screws onto that upper post part. It also includes the two doors (be sure to install the doors before tightening all the screws, as you will need to slightly pull the side to get the door pins in their holes), 3 bolts that go through the plastic upper pole into your 4x4, and 4 long screws that go through the mailbox body into the mailbox bottom (that is part of the top post). None of the holes are pre-drilled, and it takes a little work to get the bolts/screws in. You definitely will need a drill, and you could pre-drill the holes, although I just used the included bolts and screws to make their own holes. For that reason, I have only 3 stars for easy of assembly. The 4x4 will fit tightly at first through the bottom part of the post, where it connects to the top part. However, during installation, I found that once I had put the post through, after that the plastic expanded slightly to fit perfectly. The red flag is already incorporated in to the mailbox side. The mailbox is very deep, from front to back. I made some changes to installation to make it sturdier. I buried the bottom 5" of the plastic post in the ground and filled the bottom part of the plastic post with sand/dirt (I live in FL, where we have sand) to give it more stability (I'm sure it would have been stable without doing this, but I wanted to make it even more so). I also put 2 additional bolts in the front (the mailbox comes supplied with 3 bolts that go in the back), because I felt it moved around to much between the post sections, with only the bolts on the back. With these improvements, it's rock solid! Also, another reviewer stated that the door rubs against the sides. This is true when it's not installed. After installation they open and close fine. It makes me wonder if they wrote that review before installing. Also, the magnetic door clasps grabs nicely, and I have no concern about the doors accidentally opening. This plastic mailbox replaced a metal one. I have two Step2 Mailbox Minders (door alarms) that I purchased years ago. The Mailbox Minder works better in the plastic one (less blockage of the radio transmission). Since this new mailbox has 2 doors, I am putting a Mailbox Minder on each door, for security. This Step2 mailbox is MADE IN THE USA in Ohio.

We recently upgraded our front yard and wanted a different but practical mailbox. This one caught our eye. Easy to install. Solid bolts to hold the mailbox together. You will need 20V battery drill. Digging for the post is the hard part. Let's see how it holds up in tough Alberta winter.

Had a fish mailbox before and it would leak... this is super sturdy and will be weather proof here in Canada. Love it. My ONLY wish is that there was a factory way to seal the back door, which isn't useful in my situation.

Was easy enough to assemble, seems sturdy enough but light weight plastic somewhat, so hasn't been tested in high winds. Very happy with purchase. Glad I finally got around to it, our old mailbox was in pretty rough shape.

Easy to assemble,. digging the hole was the hard part. Looks fine. Looks sturdy. Put in a few extra screws. Only problem is the molded-in US Mail label as I live in Canada.
