  1. James L. (Paul’s Best Lawn Service, Inc) (verified owner)

    Great product, and very easy to place the order. Product arrived on time and free of defects. Highly recommend.

  2. Steve S. (w/Schafer Development Co.) (verified owner)

    Great, sturdy mailboxes that arrived quickly! One of the mailboxes was missing the the magnetic latch to keep the door closed so we rigged an alternative until we received the part. Brianna in customer support answered me quickly and got us what we needed. I would definitely do business again here again and recommend.

  3. Donna G. (w/Legacy Bible Church) (verified owner)

    I can’t really comment. Unfortunately we were unable to install the box as we are on a county road and are forbidden to have a box this size. Box looks nice but I will never get to know how it worked. We purchased as it was recommended by someone else and I know they are very happy with their purchase. Would advise future buyers to check with your local equivalent to our Tx Dept of Transportation before purchasing.

  7. Anonymous (verified owner)

    Exactly as described on website. Very happy with my purchase

  8. Chris D. (W/Disilva Transportation) (verified owner)

    Great product, easy to assemble and mount

  9. John T. (w/Trinity Church) (verified owner)

    Solid construction. Easy to set up and install. The mail box comes with 4 medium sized screws that secure the top to the vertical post plate. I added 4 big bolts with nylon nuts to the additional holes that were already notched in the mail box head and the vertical post plate. Much more secure and stable. It is everything that was advertised and we are extremely happy with the purchase.
