              When installed, the mailbox does not even touch the main post. Just sticks out in the air on the support arm. Is this right?

                  EXTREMELY FLIMSY
                  Extremely flimsy! The connection between the post and the bracket arm was welded poorly. It will rust after a while then break off.

                    The pole was awesome. It went well into the ground and fit our mailbox well. Really like that it’s metal and not wood.

                    Pounding block broke during instalation
                    This will do the job if you're looking for a simple dive-in mailbox post. However, adjust when installing on dry/hard ground. The bottom post was able to work its way through the pounding block before it was no more than 6 inches in the ground. I was able to improvise to get it a few more inches down, and thanks to the height flexibility of the cross-arm, I could adjust the height of my mailbox to be USPS compliant. All in all, it requires some manual labor but does the job.

                      Great sturdy, affordable mailbox post
                      I was looking for an affordable post that I, a 56 yr old woman, could install on my own - after a car wreck took out my old mailbox. This was PERFECT!!! It assembles easily and pounds into the ground easily also. NO messy concrete is needed. It looks great, and i am so happy with it. It feels super sturdy when i open and close the mailbox, just as sturdy as if it had concrete holding it. Awesome product I highly reccommend!!!

                        This was so simple to put up. Cheap enough to replace also, if another snowplow hits it. I love the adjustable height also. It comes with a solid plastic block to hit on, when hammering it into the ground. I highly recommend it!!!

                        I had the same post already, but the first only lasted about 3 years,the bracket rusted off. The post was still good, all I needed was the bracket but you can't buy parts separate, and its still winter I i wasn't driving anything in the ground I had to buy the whole thing. This summer I will be replacing it with something made a lot better.

                          Rusted and Broke After Only 3 Years - Good While It Lasted...
                          Installation was fairly easy. The “sharp” (angle-cut) end was easy to drive into the ground. The mounting hardware was a bit awkward to assemble onto the box (which might be unavoidable since the post could accommodate several models of boxes with differing mounting holes). My complaint (and the reason for the review coming a few years after installation) is that the angled arm that supports the box broke off (dropping the box to the ground) when retrieving the mail after only 3 years of service. It was plain to see that the black paint (applied by the factory) provided insufficient protection from water and the parts rusted until they could no longer take the load. Now we may have to wait several days to discover how much we won in the Publishers Clearing House Sweepstakes. The box was installed roadside in eastern Massachusetts and was exposed to a modest amount of road salting during 3 winters. However, I think it is reasonable to expect considerably more than 3 years of service from a product of this price. It did look fine and work well until it broke, and it might well survive a lot longer in an arid climate (or at least where no salting is applied in the vicinity). Good luck! :-)
