Rated 4.8 out of 5 by 41 reviewers.
Rated 5.0 out of 5.0 by THE Mailbox for home business! I had one of these at my former home and it lasted some 20 years without a problem. It is perfect if you receive magazines or anything in a large envelope as they will lay flat in the mailbox. The 'door opened' indicator is great for saving trips to the mailbox to see if the mail carrier has stopped. SO happy they still make this for my NEW home!!! February 11, 2014
Rated 5.0 out of 5.0 by Best mailbox we've ever had. We've had this mailbox at our last three homes and will certainly buy it again if we ever need another one. It's a good bit wider than a conventional mailbox so magazines etc. lay flat when put inside. The additional space also allows the mailman to put boxes and it instead of putting them on the front porch or leaving a slip to pick it up later. Combining that with this great price and the fact that it holds up very well to all weather conditions makes a great combination. April 14, 2015
Rated 5.0 out of 5.0 by Functional Purchase I bought this mailbox because it was similar to the mailbox that we used until recently. My brother put the mailbox up and although a cement base was later added around the mailbox for stability, the product turned out to be very functional. Since I receive a lot of packages (sometimes delivered by USPS), the mailbox I would choose would have to be wide enough for some packages. This mailbox fit that need very well and has room left for our regular mail. Overall, this mailbox is both functional and serves our needs quite well. September 23, 2015
Rated 5.0 out of 5.0 by DURABLE AND BEST MAILBOX EVER Purchased this to replace a hit and run mailbox... all I can say is that it is durable Installed it mid November and December 25th it was hit again... NO damage at all just loosened the 4x4 post and had to reattach the mailbox lid.... works just fine I did move the mailbox back 1.5 feet to make sure that it is not as close to the street again.. MOST DEF BUY THIS!!!! December 29, 2013
Rated 5.0 out of 5.0 by Best available! Recommend highly! I have purchased three of these over the years. Three years ago, I sold the house where I installed the first one. One of the first things I did was purchase and install one at my new home. Hurricanes couldn't blow it down, falling trees couldn't crush it. It took a trash truck running over it to take it out of commission (I now use it outside my back door to stage things which need to go to my workshop. The week after installing the new one at the end of my driveway, the same trash truck claimed a return match, but couldn't get the job done. The Roughneck prevailed. If ever Godzilla comes through and stomps it, I will buy my fourth. You can't do better than this. November 13, 2012
Rated 4.0 out of 5.0 by Functions well Easy to assemble and install. Can't seem to get the address numbers to stick, but that's not the fault of the mailbox. Be careful when installing - too tight a screw in one place can skew the mailbox on the post so the door won't close properly. September 6, 2015
Rated 5.0 out of 5.0 by Best $30 Mailbox Available Just installed the 2nd one, after a vehicle took out the 1st one. Had the 1st one for about 15 years with never a problem. Door still worked like new, even the flags were still functional. Didn't hesitate for a moment when I found the same model still available. The only issue you'll have with this mailbox, it will fade if installed in direct full sun. But you can return it to its original shade with a vinyl treatment, like you would use on the black plastic on your car. Installs easily - directly on a standard 4x4 - no special bracket needed. Note: Mounting screws are not included. December 21, 2013
Rated 5.0 out of 5.0 by A little larger than standard rural Mailbox I bought the previous version of this box over twenty years ago and other than it starting to look a little weather warn from the sun, I would have been still using it. I replaced it after road equipment knocked down the mailbox post and decided it was time. The box was still in usable shape. The arm on the box lets you see if mail has arrived. If you prefer not to use it, you can take it off. It is larger than standard and allows for larger packages to be delivered. You do not need the bracket sold separately to mount in most applications.
