[This review was collected as part of a promotion.] I work for a company that receives many payments and adding this large drop box to the outside of our door has been so helpful! Customers can drop off payments or important forms and it is safely in the drop box. It was easy to mount to the door. The key works wonderfully and it’s nice to have a back up code entry for when the key is not accessible. I would recommend this box to anyone needing a way for customers to drop items off (forms, payment, keys etc.) after hours or on lunch breaks.. Nep723. Fishers Island Ny. Thu Jul 07 2022

It's beautiful but quite disppointed that it arrived dented and there is paint missing where it is dented. The dent also created a gap on the from of the mailbox. Also, the description said it came with the post. After waiting over a month for the mailbox to arrive, it arrived without the post and dented. Other than that, the box is offers a clean and modern aesthetic.. Katia. Doral, FL. Wed Sep 24 2025
